Bug 657748 - Update ANGLE to r653 - a=joe This ANGLE update fixes bugs, brings large performance improvements, and adds major new features that web devs are looking forward to: vertex shader texture lookup and float textures. http://code.google.com/p/angleproject/ This update is also needed because the version we're currently using is the chrome_m10 branch and that's no longer maintained. This update will make it much easier to apply security fixes if needed.

 This is the ANGLE project, from http://code.google.com/p/angleproject/.
 
-Current revision: r550
+Current revision: r653
 
-Applied local patches:
-    angle-shared.patch - add declspec dllexport/dllimport support on win32
+== Applied local patches ==
 
-    angle-fixes.patch - fix angle issues 51 & 52
+In this order:
+  angle-nspr-misc.patch - don't bother with ANGLE_OS detection with NSPR
+  angle-renaming.patch - rename debug.h to compilerdebug.h to avoid conflict in our makefiles
+  angle-makefiles.patch - Mozilla Makefiles for ANGLE
 
-    angle-nspr-misc.patch - don't bother with ANGLE_OS detection with NSPR
+== How to update this ANGLE copy ==
 
-    angle-pbuffers.patch - add pbuffer support to ANGLE, and d3d texture handle query (angle issue 91)
+1. Unapply patches
+2. Apply diff with new ANGLE version
+3. Reapply patches. Check for newly created/deleted files.
+4. For each file creation/deletetion recorded in step 3, update our makefiles (angle-makefiles.patch) accordingly
 
 == Visual Studio Solution Files ==
 
-The VS solution/project files that are used to build ANGLE are built
-with VS2008 in upstream ANGLE.  Because our build machines use VS2005,
-they need to be downgraded using
-http://www.emmet-gray.com/Articles/ProjectConverter.htm before being
-checked in with an ANGLE update.
+Ignore these. We don't use them anymore. We use custom Makefiles (see angle-makefiles.patch)
 
-== Regenerating Parser ==
+== Generated parser code==
 
-The parser is now generated and included in the ANGLE svn repo.
+Don't bother about that anymore. The parser is now generated and included in the ANGLE svn repo.

+
+Status
+
+    Implemented in ANGLE ES2
+
+Version
+
+    Last Modified Date: Aug 6, 2010
+    Author Revision: 3
+
+Number
+
+    OpenGL ES Extension #83
+
+Dependencies
+
+    OpenGL ES 2.0 is required.
+
+    The extension is written against the OpenGL ES 2.0 specification.
+
+    OES_texture_3D affects the definition of this extension.
+
+Overview
+
+    This extension modifies framebuffer objects by splitting the
+    framebuffer object binding point into separate DRAW and READ
+    bindings.  This allows copying directly from one framebuffer to
+    another.  In addition, a new high performance blit function is
+    added to facilitate these blits and perform some data conversion
+    where allowed.
+
+IP Status
+
+    No known IP claims.
+
+New Procedures and Functions
+
+    void BlitFramebufferANGLE(int srcX0, int srcY0, int srcX1, int srcY1,
+                              int dstX0, int dstY0, int dstX1, int dstY1,
+                              bitfield mask, enum filter);
+
+New Tokens
+
+    Accepted by the <target> parameter of BindFramebuffer,
+    CheckFramebufferStatus, FramebufferTexture2D, FramebufferTexture3DOES,
+    FramebufferRenderbuffer, and
+    GetFramebufferAttachmentParameteriv:
+
+    // (reusing the tokens from EXT_framebuffer_blit)
+    READ_FRAMEBUFFER_ANGLE                0x8CA8
+    DRAW_FRAMEBUFFER_ANGLE                0x8CA9
+
+    Accepted by the <pname> parameters of GetIntegerv and GetFloatv:
+
+    // (reusing the tokens from EXT_framebuffer_blit)
+    DRAW_FRAMEBUFFER_BINDING_ANGLE        0x8CA6 // alias FRAMEBUFFER_BINDING
+    READ_FRAMEBUFFER_BINDING_ANGLE        0x8CAA
+
+
+Additions to Chapter 3 of the OpenGL ES 2.0 Specification (Rasterization)
+
+    Change the last paragraph of section 3.7.2 (Alternate Texture Image
+    Specification Commands) to:
+
+    "Calling CopyTexSubImage3DOES, CopyTexImage2D or CopyTexSubImage2D will
+    result in an INVALID_FRAMEBUFFER_OPERATION error if the object bound
+    to READ_FRAMEBUFFER_BINDING_ANGLE is not "framebuffer complete"
+    (section 4.4.4.2)."
+
+Additions to Chapter 4 of the OpenGL ES 2.0 Specification (Per-Fragment
+Operations and the Framebuffer)
+
+    Change the first word of Chapter 4 from "The" to "A".
+
+    Append to the introduction of Chapter 4:
+
+    "Conceptually, the GL has two active framebuffers; the draw
+    framebuffer is the destination for rendering operations, and the
+    read framebuffer is the source for readback operations.  The same
+    framebuffer may be used for both drawing and reading.  Section
+    4.4.1 describes the mechanism for controlling framebuffer usage."
+
+    Modify the first sentence of the last paragraph of section 4.1.1 as follows:
+
+    "While an application-created framebuffer object is bound to
+    DRAW_FRAMEBUFFER_ANGLE, the pixel ownership test always passes."
+
+    Add to 4.3.1 (Reading Pixels), right before the subsection titled
+    "Obtaining Pixels from the Framebuffer":
+
+    "Calling ReadPixels generates INVALID_FRAMEBUFFER_OPERATION if
+    the object bound to READ_FRAMEBUFFER_BINDING_ANGLE is not "framebuffer
+    complete" (section 4.4.4.2)."
+
+    Insert a new section 4.3.2 titled "Copying Pixels" and renumber the
+    subsequent sections.  Add the following text:
+
+    "BlitFramebufferANGLE transfers a rectangle of pixel values from one
+    region of the read framebuffer to another in the draw framebuffer.
+
+    BlitFramebufferANGLE(int srcX0, int srcY0, int srcX1, int srcY1,
+                         int dstX0, int dstY0, int dstX1, int dstY1,
+                         bitfield mask, enum filter);
+
+    <mask> is the bitwise OR of a number of values indicating which
+    buffers are to be copied. The values are COLOR_BUFFER_BIT,
+    DEPTH_BUFFER_BIT, and STENCIL_BUFFER_BIT, which are described in
+    section 4.2.3.  The pixels corresponding to these buffers are
+    copied from the source rectangle, bound by the locations (srcX0,
+    srcY0) and (srcX1, srcY1), to the destination rectangle, bound by
+    the locations (dstX0, dstY0) and (dstX1, dstY1).  The lower bounds
+    of the rectangle are inclusive, while the upper bounds are
+    exclusive.
+
+    The actual region taken from the read framebuffer is limited to the
+    intersection of the source buffers being transferred, which may include
+    the color buffer, the depth buffer, and/or the stencil buffer depending on
+    <mask>. The actual region written to the draw framebuffer is limited to the
+    intersection of the destination buffers being written, which may include
+    the color buffer, the depth buffer, and/or the stencil buffer
+    depending on <mask>. Whether or not the source or destination regions are
+    altered due to these limits, the offset applied to pixels being transferred
+    is performed as though no such limits were present.
+
+    Stretching and scaling during a copy are not supported. If the source
+    and destination rectangle dimensions do not match, no copy is
+    performed and an INVALID_OPERATION error is generated.
+    Because stretching is not supported, <filter> must be NEAREST and
+    no filtering is applied. 
+
+    Flipping during a copy is not supported. If either the source or 
+    destination rectangle specifies a negative dimension, the error 
+    INVALID_OPERATION is generated. If both the source and 
+    destination rectangles specify a negative dimension for the same 
+    direction, no reversal is required and the operation is supported.
+
+    If the source and destination buffers are identical, and the
+    source and destination rectangles overlap, the result of the blit
+    operation is undefined.
+
+    The pixel copy bypasses the fragment pipeline.  The only fragment
+    operations which affect the blit are the pixel ownership test and
+    the scissor test.
+
+    If a buffer is specified in <mask> and does not exist in both the
+    read and draw framebuffers, the corresponding bit is silently
+    ignored.
+
+    Calling BlitFramebufferANGLE will result in an
+    INVALID_FRAMEBUFFER_OPERATION error if the objects bound to
+    DRAW_FRAMEBUFFER_BINDING_ANGLE and READ_FRAMEBUFFER_BINDING_ANGLE are
+    not "framebuffer complete" (section 4.4.4.2)."
+
+    Calling BlitFramebufferANGLE will result in an INVALID_OPERATION
+    error if <mask> includes COLOR_BUFFER_BIT and the source and 
+    destination color formats to not match.
+
+    Calling BlitFramebufferANGLE will result in an INVALID_OPERATION
+    error if <mask> includes DEPTH_BUFFER_BIT or STENCIL_BUFFER_BIT
+    and the source and destination depth and stencil buffer formats do
+    not match.
+
+    If <mask> includes DEPTH_BUFFER_BIT or STENCIL_BUFFER_BIT, only 
+    complete buffers can be copied.  If the source rectangle does not 
+    specify the complete source buffer or the destination rectangle 
+    (after factoring the scissor region, if applicable) does not specify 
+    the complete destination buffer, an INVALID_OPERATION
+    error is generated.
+
+    Modify the beginning of section 4.4.1 as follows:
+
+    "The default framebuffer for rendering and readback operations is
+    provided by the windowing system.  In addition, named framebuffer
+    objects can be created and operated upon.  The namespace for
+    framebuffer objects is the unsigned integers, with zero reserved
+    by the GL for the default framebuffer.
+
+    A framebuffer object is created by binding an unused name to
+    DRAW_FRAMEBUFFER_ANGLE or READ_FRAMEBUFFER_ANGLE.  The binding is
+    effected by calling
+
+        void BindFramebuffer(enum target, uint framebuffer);
+
+    with <target> set to the desired framebuffer target and
+    <framebuffer> set to the unused name.  The resulting framebuffer
+    object is a new state vector, comprising one set of the state values
+    listed in table 6.23 for each attachment point of the
+    framebuffer, set to the same initial values.  There is one
+    color attachment point, plus one each
+    for the depth and stencil attachment points.
+
+    BindFramebuffer may also be used to bind an existing
+    framebuffer object to DRAW_FRAMEBUFFER_ANGLE or
+    READ_FRAMEBUFFER_ANGLE.  If the bind is successful no change is made
+    to the state of the bound framebuffer object, and any previous
+    binding to <target> is broken.
+
+    If a framebuffer object is bound to DRAW_FRAMEBUFFER_ANGLE or
+    READ_FRAMEBUFFER_ANGLE, it becomes the target for rendering or
+    readback operations, respectively, until it is deleted or another
+    framebuffer is bound to the corresponding bind point.  Calling
+    BindFramebuffer with <target> set to FRAMEBUFFER binds the
+    framebuffer to both DRAW_FRAMEBUFFER_ANGLE and READ_FRAMEBUFFER_ANGLE.
+
+    While a framebuffer object is bound, GL operations on the target
+    to which it is bound affect the images attached to the bound
+    framebuffer object, and queries of the target to which it is bound
+    return state from the bound object.  Queries of the values
+    specified in table 6.20 (Implementation Dependent Pixel Depths)
+    and table 6.yy (Framebuffer Dependent Values) are
+    derived from the framebuffer object bound to DRAW_FRAMEBUFFER_ANGLE.
+
+    The initial state of DRAW_FRAMEBUFFER_ANGLE and READ_FRAMEBUFFER_ANGLE
+    refers to the default framebuffer provided by the windowing
+    system.  In order that access to the default framebuffer is not
+    lost, it is treated as a framebuffer object with the name of 0.
+    The default framebuffer is therefore rendered to and read from
+    while 0 is bound to the corresponding targets.  On some
+    implementations, the properties of the default framebuffer can
+    change over time (e.g., in response to windowing system events
+    such as attaching the context to a new windowing system drawable.)"
+
+    Change the description of DeleteFramebuffers as follows:
+
+    "<framebuffers> contains <n> names of framebuffer objects to be
+    deleted.  After a framebuffer object is deleted, it has no
+    attachments, and its name is again unused.  If a framebuffer that
+    is currently bound to one or more of the targets
+    DRAW_FRAMEBUFFER_ANGLE or READ_FRAMEBUFFER_ANGLE is deleted, it is as
+    though BindFramebuffer had been executed with the corresponding
+    <target> and <framebuffer> zero.  Unused names in <framebuffers>
+    are silently ignored, as is the value zero."
+
+
+    In section 4.4.3 (Renderbuffer Objects), modify the first two sentences
+    of the description of FramebufferRenderbuffer as follows:
+
+    "<target> must be DRAW_FRAMEBUFFER_ANGLE, READ_FRAMEBUFFER_ANGLE, or
+    FRAMEBUFFER.  If <target> is FRAMEBUFFER, it behaves as
+    though DRAW_FRAMEBUFFER_ANGLE was specified.  The INVALID_OPERATION 
+    error is generated if the value of the corresponding binding is zero."
+
+    In section 4.4.3 (Renderbuffer Objects), modify the first two sentences
+    of the description of FramebufferTexture2D as follows:
+
+    "<target> must be DRAW_FRAMEBUFFER_ANGLE,
+    READ_FRAMEBUFFER_ANGLE, or FRAMEBUFFER.  If <target> is
+    FRAMEBUFFER, it behaves as though DRAW_FRAMEBUFFER_ANGLE was
+    specified.  The INVALID_OPERATION error is generated if the value of the
+    corresponding binding is zero."
+
+    In section 4.4.5 (Framebuffer Completeness), modify the first sentence 
+    of the description of CheckFramebufferStatus as follows:
+
+    "If <target> is not DRAW_FRAMEBUFFER_ANGLE, READ_FRAMEBUFFER_ANGLE or
+    FRAMEBUFFER, the error INVALID_ENUM is generated.  If <target> is
+    FRAMEBUFFER, it behaves as though DRAW_FRAMEBUFFER_ANGLE was
+    specified."
+
+    Modify the first sentence of the subsection titled "Effects of Framebuffer
+    Completeness on Framebuffer Operations" to be:
+
+    "Attempting to render to or read from a framebuffer which is not
+    framebuffer complete will generate an
+    INVALID_FRAMEBUFFER_OPERATION error."
+    
+
+
+Additions to Chapter 6 of the OpenGL 1.5 Specification (State and State
+Requests)
+
+    In section 6.1.3, modify the first sentence of the description of
+    GetFramebufferAttachmentParameteriv as follows:
+
+    "<target> must be DRAW_FRAMEBUFFER_ANGLE, READ_FRAMEBUFFER_ANGLE or
+    FRAMEBUFFER.  If <target> is FRAMEBUFFER, it behaves as
+    though DRAW_FRAMEBUFFER_ANGLE was specified."
+
+    Modify the title of Table 6.23 (Framebuffer State) to be "Framebuffer 
+    (state per attachment point)".

+
+    The error INVALID_OPERATION is generated if BlitFramebufferANGLE is

+
+
+Issues
+
+    1) What should we call this extension?
+  
+       Resolved: ANGLE_framebuffer_blit.  
+
+       This extension is a result of a collaboration between Google and 
+       TransGaming for the open-source ANGLE project. Typically one would
+       label a multi-vendor extension as EXT, but EXT_framebuffer_blit 
+       is already the name for this on Desktop GL.  Additionally this
+       isn't truely a multi-vendor extension because there is only one
+       implementation of this.  We'll follow the example of the open-source
+       MESA project which uses the project name for the vendor suffix.
+
+    2) Why is this done as a separate extension instead of just supporting
+       EXT_framebuffer_blit?
+
+       To date, EXT_framebuffer_blit has not had interactions with OpenGL ES
+       specified and, as far as we know, it has not previously been exposed on 
+       an ES 1.1 or ES 2.0 implementation. Because there are enough 
+       differences between Desktop GL and OpenGL ES, and since OpenGL ES 2.0 
+       has already subsumed the EXT_framebuffer_object functionality (with 
+       some changes) it was deemed a worthwhile exercise to fully specify the
+       interactions.  Additionally, some of the choices in exactly which 
+       functionality is supported by BlitFramebufferANGLE is dictated by
+       what is reasonable to support on a implementation which is 
+       layered on Direct3D9.  It is not expected that other implementations 
+       will necessary have the same set of restrictions or requirements. 
+
+    3) How does this extension differ from EXT_framebuffer_blit?
+
+       This extension is designed to be a pure subset of the 
+       EXT_framebuffer_blit functionality as applicable to OpenGL ES 2.0.
+
+       Functionality that is unchanged:
+        - the split DRAW and READ framebuffer attachment points and related sematics.
+        - the token values for the DRAW/READ_FRAMEBUFFER and DRAW/READ_FRAMBUFFER_BINDING
+        - the signature of the BlitFramebuffer entry-point.
+       
+       Additional restrictions imposed by BlitFramebufferANGLE:
+        - no color conversions are supported
+        - no scaling, stretching or flipping are supported
+        - no filtering is supported (a consequence of no stretching)
+        - only whole depth and/or stencil buffers can be copied

+
+    The extension is written against the OpenGL ES 2.0 specification.

+
+Overview
+
+    This extension extends the framebuffer object framework to
+    enable multisample rendering.
+
+    The new operation RenderbufferStorageMultisampleANGLE() allocates
+    storage for a renderbuffer object that can be used as a multisample
+    buffer.  A multisample render buffer image differs from a
+    single-sample render buffer image in that a multisample image has a
+    number of SAMPLES that is greater than zero.  No method is provided
+    for creating multisample texture images.
+
+    All of the framebuffer-attachable images attached to a framebuffer
+    object must have the same number of SAMPLES or else the framebuffer
+    object is not "framebuffer complete".  If a framebuffer object with
+    multisample attachments is "framebuffer complete", then the
+    framebuffer object behaves as if SAMPLE_BUFFERS is one.
+
+    The resolve operation is affected by calling 
+    BlitFramebufferANGLE (provided by the ANGLE_framebuffer_blit
+    extension) where the source is a multisample application-created
+    framebuffer object and the destination is a single-sample
+    framebuffer object (either application-created or window-system
+    provided).
+

+Additions to Chapter 2 of the OpenGL ES 2.0 Specification (OpenGL Operation)
+
+Additions to Chapter 3 of the OpenGL ES 2.0 Specification (Rasterization)
+
+    Add to the last paragraph of 3.7.2 (Alternate Texture Image Specification)
+    (as modified by ANGLE_framebuffer_blit) the following:
+
+    "Calling CopyTexSubImage3DOES, CopyTexImage2D or CopyTexSubImage2D will
+    result in INVALID_OPERATION being generated if the object bound to
+    READ_FRAMEBUFFER_BINDING_ANGLE is "framebuffer complete" and the value
+    of SAMPLE_BUFFERS is greater than zero."
+
+Additions to Chapter 4 of the OpenGL ES 2.0 Specification (Per-Fragment
+Operations and the Framebuffer)
+
+    Add to 4.3.1 (Reading Pixels), right before the subsection titled
+    "Obtaining Pixels from the Framebuffer":
+
+    "ReadPixels generates INVALID_OPERATION if READ_FRAMEBUFFER_BINDING_ANGLE
+    (section 4.4) is non-zero, the read framebuffer is framebuffer
+    complete, and the value of SAMPLE_BUFFERS for the read framebuffer
+    is greater than zero."
+
+    In 4.3.2 (Copying Pixels), add to the section describing BlitFramebuffer
+    that was added by ANGLE_framebuffer_blit.
+
+    "If SAMPLE_BUFFERS for the read framebuffer is greater than zero and
+    SAMPLE_BUFFERS for the draw framebuffer is zero, the samples
+    corresponding to each pixel location in the source are converted to
+    a single sample before being written to the destination.
+
+    If SAMPLE_BUFFERS for the draw framebuffer is greater than zero, 
+    no copy is performed and an INVALID_OPERATION error is generated.
+
+    If SAMPLE_BUFFERS for the read framebuffer is greater than zero and
+    <mask> includes DEPTH_BUFFER_BIT or STENCIL_BUFFER_BIT, no copy is 
+    performed and an INVALID_OPERATION error is generated.
+
+    If SAMPLE_BUFFERS for the read framebuffer is greater than zero and 
+    the format of the read and draw framebuffers are not identical, no
+    copy is performed and an INVALID_OPERATION error is generated.
+
+    If SAMPLE_BUFFERS for the read framebuffer is greater than zero, the
+    dimensions of the source and destination rectangles provided to 
+    BlitFramebufferANGLE must be identical and must specify the complete 
+    source and destination buffers, otherwise no copy is performed and 
+    an INVALID_OPERATION error is generated."
+
+    Modification to 4.4.3 (Renderbuffer Objects)
+
+    Add, just above the definition of RenderbufferStorage:
+
+    "The command
+
+        void RenderbufferStorageMultisampleANGLE(
+            enum target, sizei samples,
+            enum internalformat,
+            sizei width, sizei height);
+
+    establishes the data storage, format, dimensions, and number of
+    samples of a renderbuffer object's image.  <target> must be
+    RENDERBUFFER.  <internalformat> must be one of the color-renderable,
+    depth-renderable, or stencil-renderable formats described in table 4.5.
+    <width> and <height> are the dimensions in pixels of the renderbuffer.  If
+    either <width> or <height> is greater than the value of 
+    MAX_RENDERBUFFER_SIZE, or if <samples> is greater than MAX_SAMPLES_ANGLE, 
+    then the error INVALID_VALUE is generated. If OpenGL ES is unable to 
+    create a data store of the requested size, the error OUT_OF_MEMORY 
+    is generated.
+
+    Upon success, RenderbufferStorageMultisampleANGLE deletes any existing
+    data store for the renderbuffer image and the contents of the data
+    store after calling RenderbufferStorageMultisampleANGLE are undefined.
+    RENDERBUFFER_WIDTH is set to <width>, RENDERBUFFER_HEIGHT is
+    set to <height>, and RENDERBUFFER_INTERNAL_FORMAT is set to
+    <internalformat>.
+
+    If <samples> is zero, then RENDERBUFFER_SAMPLES_ANGLE is set to zero.
+    Otherwise <samples> represents a request for a desired minimum
+    number of samples. Since different implementations may support
+    different sample counts for multisampled rendering, the actual
+    number of samples allocated for the renderbuffer image is
+    implementation dependent.  However, the resulting value for
+    RENDERBUFFER_SAMPLES_ANGLE is guaranteed to be greater than or equal
+    to <samples> and no more than the next larger sample count supported
+    by the implementation.
+
+    An OpenGL ES implementation may vary its allocation of internal component
+    resolution based on any RenderbufferStorageMultisampleANGLE parameter (except
+    target), but the allocation and chosen internal format must not be a
+    function of any other state and cannot be changed once they are
+    established. The actual resolution in bits of each component of the 
+    allocated image can be queried with GetRenderbufferParameteriv."
+
+    Modify the definiton of RenderbufferStorage as follows:
+
+    "The command
+
+        void RenderbufferStorage(enum target, enum internalformat,
+                                    sizei width, sizei height);
+
+     is equivalent to calling RenderbufferStorageMultisampleANGLE with
+     <samples> equal to zero."
+
+    In section 4.4.5 (Framebuffer Completeness) in the subsection
+    titled "Framebuffer Completeness" add an entry to the bullet list:
+
+    * The value of RENDERBUFFER_SAMPLES_ANGLE is the same for all attached
+      images.
+      { FRAMEBUFFER_INCOMPLETE_MULTISAMPLE_ANGLE }
+
+    Also add a paragraph to the end of the section after the definition
+    of CheckFramebufferStatus:
+
+    "The values of SAMPLE_BUFFERS and SAMPLES are derived from the
+    attachments of the currently bound framebuffer object.  If the
+    current DRAW_FRAMEBUFFER_BINDING_ANGLE is not "framebuffer complete",
+    then both SAMPLE_BUFFERS and SAMPLES are undefined.  Otherwise,
+    SAMPLES is equal to the value of RENDERBUFFER_SAMPLES_ANGLE for the
+    attached images (which all must have the same value for
+    RENDERBUFFER_SAMPLES_ANGLE).  Further, SAMPLE_BUFFERS is one if
+    SAMPLES is non-zero.  Otherwise, SAMPLE_BUFFERS is zero.
+
+Additions to Chapter 5 of the OpenGL ES 2.0 Specification (Special Functions)
+
+
+Additions to Chapter 6 of the OpenGL ES 2.0 Specification (State and State
+Requests)
+
+    In section 6.1.3 (Enumeraged Queries), modify the third paragraph 
+    of the description of GetRenderbufferParameteriv as follows:
+
+    "Upon successful return from GetRenderbufferParameteriv, if
+    <pname> is RENDERBUFFER_WIDTH, RENDERBUFFER_HEIGHT,
+    RENDERBUFFER_INTERNAL_FORMAT, or RENDERBUFFER_SAMPLES_ANGLE, then <params> 
+    will contain the width in pixels, height in pixels, internal format, or 
+    number of samples, respectively, of the image of the renderbuffer 
+    currently bound to <target>."
+
+
+Dependencies on ANGLE_framebuffer_blit    
+
+    ANGLE_framebuffer_blit is required.  Technically, ANGLE_framebuffer_blit
+    would not be required to support multisampled rendering, except for
+    the fact that it provides the only method of doing a multisample
+    resovle from a multisample renderbuffer.
+
+Dependencies on OES_texture_3D
+
+    On an OpenGL ES implementation, in the absense of OES_texture_3D,
+    omit references to CopyTexSubImage3DOES.
+
+Errors
+
+    The error INVALID_OPERATION is generated if ReadPixels or 
+    CopyTex{Sub}Image* is called while READ_FRAMEBUFFER_BINDING_ANGLE
+    is non-zero, the read framebuffer is framebuffer complete, and the
+    value of SAMPLE_BUFFERS for the read framebuffer is greater than
+    zero.
+
+    If both the draw and read framebuffers are framebuffer complete and
+    the draw framebuffer has a value of SAMPLE_BUFFERS that is greater 
+    than zero, then the error INVALID_OPERATION is generated if 
+    BlitFramebufferANGLE is called.
+
+    If both the draw and read framebuffers are framebuffer complete and

+Issues
+    
+    Issues from EXT_framebuffer_multisample have been removed.
+ 
+    1) What should we call this extension?
+
+       Resolved: ANGLE_framebuffer_blit.  
+
+       This extension is a result of a collaboration between Google and 
+       TransGaming for the open-source ANGLE project. Typically one would
+       label a multi-vendor extension as EXT, but EXT_framebuffer_mulitsample 
+       is already the name for this on Desktop GL.  Additionally this
+       isn't truely a multi-vendor extension because there is only one
+       implementation of this.  We'll follow the example of the open-source
+       MESA project which uses the project name for the vendor suffix.
+ 
+    2) How does this extension differ from EXT_framebuffer_multisample?
+
+       This is designed to be a proper subset of EXT_framebuffer_multisample
+       functionality as applicable to OpenGL ES 2.0.
+
+       Functionality that is unchanged: 
+        - creation of multisample renderbuffers.
+        - whole buffer multi-sample->single-sample resolve.
+        - no format conversions, stretching or flipping supported on multisample blits.
+
+       Additional restrictions on BlitFramebufferANGLE:
+        - multisample resolve is only supported on color buffers.
+        - no blits to multisample destinations (no single->multi or multi-multi).
+        - only entire buffers can be resolved.
+

+    OpenGL ES Extension #??
+
+Dependencies
+
+    OpenGL ES 2.0 is required.
+
+    The extension is written against the OpenGL ES 2.0 specification.
+
+Overview
+
+    Applications can benefit from accurate timing information in a number of
+    different ways.  During application development, timing information can
+    help identify application or driver bottlenecks.  At run time,
+    applications can use timing information to dynamically adjust the amount
+    of detail in a scene to achieve constant frame rates.  OpenGL
+    implementations have historically provided little to no useful timing
+    information.  Applications can get some idea of timing by reading timers
+    on the CPU, but these timers are not synchronized with the graphics
+    rendering pipeline.  Reading a CPU timer does not guarantee the completion
+    of a potentially large amount of graphics work accumulated before the
+    timer is read, and will thus produce wildly inaccurate results.
+    glFinish() can be used to determine when previous rendering commands have
+    been completed, but will idle the graphics pipeline and adversely affect
+    application performance.
+
+    This extension provides a query mechanism that can be used to determine
+    the amount of time it takes to fully complete a set of GL commands, and
+    without stalling the rendering pipeline.  It uses the query object
+    mechanisms first introduced in the occlusion query extension, which allow
+    time intervals to be polled asynchronously by the application.
+
+IP Status
+
+    No known IP claims.

+    uint64ANGLE   64                  Unsigned binary integer
+
+Additions to Chapter 5 of the OpenGL ES 2.0 Specification (Special Functions)
+
+    Add a new section 5.3 "Timer Queries":
+
+    "5.3  Timer Queries
+
+    Timer queries use query objects to track the amount of time needed to
+    fully complete a set of GL commands, or to determine the current time
+    of the GL.
+    
+    Timer queries are associated with query objects.  The command
+
+      void GenQueriesANGLE(sizei n, uint *ids);
+
+    returns <n> previously unused query object names in <ids>.  These
+    names are marked as used, but no object is associated with them until
+    the first time they are used by BeginQueryANGLE.  Query objects contain
+    one piece of state, an integer result value.  This result value is
+    initialized to zero when the object is created.  Any positive integer
+    except for zero (which is reserved for the GL) is a valid query
+    object name.
+
+    Query objects are deleted by calling
+
+      void DeleteQueriesANGLE(sizei n, const uint *ids);
+
+    <ids> contains <n> names of query objects to be deleted.  After a
+    query object is deleted, its name is again unused.  Unused names in
+    <ids> are silently ignored.
+    If an active query object is deleted its name immediately becomes unused,
+    but the underlying object is not deleted until it is no longer active.
+
+    A timer query can be started and finished by calling
+
+      void BeginQueryANGLE(enum target, uint id);
+      void EndQueryANGLE(enum target);
+
+    where <target> is TIME_ELAPSED_ANGLE.  If BeginQueryANGLE is called
+    with an unused <id>, that name is marked as used and associated with
+    a new query object.
+    
+    If BeginQueryANGLE is called with an <id> of zero, if the active query
+    object name for <target> is non-zero, if <id> is the name of an existing
+    query object whose type does not match <target>, or if <id> is the active
+    query object name for any query type, the error INVALID_OPERATION is
+    generated.  If EndQueryANGLE is called while no query with the same target
+    is in progress, an INVALID_OPERATION error is generated.
+
+    When BeginQueryANGLE and EndQueryANGLE are called with a <target> of
+    TIME_ELAPSED_ANGLE, the GL prepares to start and stop the timer used for
+    timer queries.  The timer is started or stopped when the effects from all
+    previous commands on the GL client and server state and the framebuffer
+    have been fully realized.  The BeginQueryANGLE and EndQueryANGLE commands
+    may return before the timer is actually started or stopped.  When the timer
+    query timer is finally stopped, the elapsed time (in nanoseconds) is
+    written to the corresponding query object as the query result value, and
+    the query result for that object is marked as available.
+
+    If the elapsed time overflows the number of bits, <n>, available to hold
+    elapsed time, its value becomes undefined.  It is recommended, but not
+    required, that implementations handle this overflow case by saturating at
+    2^n - 1.
+
+    The necessary state is a single bit indicating whether an timer
+    query is active, the identifier of the currently active timer
+    query, and a counter keeping track of the time that has passed.
+
+    When the command
+
+         void QueryCounterANGLE(uint id, enum target);
+
+    is called with <target> TIMESTAMP_ANGLE, the GL records the current time
+    into the corresponding query object. The time is recorded after all
+    previous commands on the GL client and server state and the framebuffer
+    have been fully realized. When the time is recorded, the query result for
+    that object is marked available. QueryCounterANGLE timer queries can be
+    used within a BeginQueryANGLE / EndQueryANGLE block where the <target> is
+    TIME_ELAPSED_ANGLE and it does not affect the result of that query object.
+    The error INVALID_OPERATION is generated if the <id> is already in use
+    within a BeginQueryANGLE/EndQueryANGLE block."
+
+Additions to Chapter 6 of the OpenGL ES 2.0 Specification (State and State
+Requests)
+
+    Add a new section 6.1.9 "Timer Queries":
+
+    "The command
+
+      boolean IsQueryANGLE(uint id);
+
+    returns TRUE if <id> is the name of a query object.  If <id> is zero,
+    or if <id> is a non-zero value that is not the name of a query
+    object, IsQueryANGLE returns FALSE.
+
+    Information about a query target can be queried with the command
+
+      void GetQueryivANGLE(enum target, enum pname, int *params);
+
+    <target> identifies the query target and can be TIME_ELAPSED_ANGLE or
+    TIMESTAMP_ANGLE for timer queries.
+
+    If <pname> is CURRENT_QUERY_ANGLE, the name of the currently active query
+    for <target>, or zero if no query is active, will be placed in <params>.
+
+    If <pname> is QUERY_COUNTER_BITS_ANGLE, the implementation-dependent number
+    of bits used to hold the query result for <target> will be placed in
+    <params>.  The number of query counter bits may be zero, in which case
+    the counter contains no useful information.
+
+    For timer queries (TIME_ELAPSED_ANGLE and TIMESTAMP_ANGLE), if the number
+    of bits is non-zero, the minimum number of bits allowed is 30 which
+    will allow at least 1 second of timing.
+
+    The state of a query object can be queried with the commands
+
+      void GetQueryObjectivANGLE(uint id, enum pname, int *params);
+      void GetQueryObjectuivANGLE(uint id, enum pname, uint *params);
+      void GetQueryObjecti64vANGLE(uint id, enum pname, int64 *params);
+      void GetQueryObjectui64vANGLE(uint id, enum pname, uint64 *params);
+
+    If <id> is not the name of a query object, or if the query object
+    named by <id> is currently active, then an INVALID_OPERATION error is
+    generated.
+
+    If <pname> is QUERY_RESULT_ANGLE, then the query object's result
+    value is returned as a single integer in <params>. If the value is so
+    large in magnitude that it cannot be represented with the requested type,
+    then the nearest value representable using the requested type is
+    returned. If the number of query counter bits for target is zero, then
+    the result is returned as a single integer with the value zero.
+    
+    There may be an indeterminate delay before the above query returns. If
+    <pname> is QUERY_RESULT_AVAILABLE_ANGLE, FALSE is returned if such a delay
+    would be required; otherwise TRUE is returned. It must always be true
+    that if any query object returns a result available of TRUE, all queries
+    of the same type issued prior to that query must also return TRUE.
+
+    Querying the state for a given timer query forces that timer query to
+    complete within a finite amount of time.
+
+    If multiple queries are issued on the same target and id prior to 
+    calling GetQueryObject[u]i[64]vANGLE, the result returned will always be
+    from the last query issued.  The results from any queries before the
+    last one will be lost if the results are not retrieved before starting
+    a new query on the same <target> and <id>."
+

+
+Examples
+
+    (1) Here is some rough sample code that demonstrates the intended usage
+        of this extension.
+
+        GLint queries[N];
+        GLint available = 0;
+        // timer queries can contain more than 32 bits of data, so always
+        // query them using the 64 bit types to avoid overflow
+        GLuint64ANGLE timeElapsed = 0;
+
+        // Create a query object.
+        glGenQueriesANGLE(N, queries);
+
+        // Start query 1
+        glBeginQueryANGLE(GL_TIME_ELAPSED_ANGLE, queries[0]);
+
+        // Draw object 1
+        ....
+
+        // End query 1
+        glEndQueryANGLE(GL_TIME_ELAPSED_ANGLE);
+
+        ...
+
+        // Start query N
+        glBeginQueryANGLE(GL_TIME_ELAPSED_ANGLE, queries[N-1]);
+
+        // Draw object N
+        ....
+
+        // End query N
+        glEndQueryANGLE(GL_TIME_ELAPSED_ANGLE);
+
+        // Wait for all results to become available
+        while (!available) {
+            glGetQueryObjectivANGLE(queries[N-1], GL_QUERY_RESULT_AVAILABLE_ANGLE, &available);
+        }
+
+        for (i = 0; i < N; i++) {
+            // See how much time the rendering of object i took in nanoseconds.
+            glGetQueryObjectui64vANGLE(queries[i], GL_QUERY_RESULT_ANGLE, &timeElapsed);
+
+            // Do something useful with the time.  Note that care should be
+            // taken to use all significant bits of the result, not just the
+            // least significant 32 bits.
+            AdjustObjectLODBasedOnDrawTime(i, timeElapsed);
+        }
+
+        This example is sub-optimal in that it stalls at the end of every
+        frame to wait for query results.  Ideally, the collection of results
+        would be delayed one frame to minimize the amount of time spent
+        waiting for the GPU to finish rendering.
+        
+    (2) This example is basically the same as the example above but uses
+        QueryCounter instead.
+    
+        GLint queries[N+1];
+        GLint available = 0;
+        // timer queries can contain more than 32 bits of data, so always
+        // query them using the 64 bit types to avoid overflow
+        GLuint64ANGLE timeStart, timeEnd, timeElapsed = 0;
+
+        // Create a query object.
+        glGenQueriesANGLE(N+1, queries);
+
+        // Query current timestamp 1
+        glQueryCounterANGLE(queries[0], GL_TIMESTAMP_ANGLE);
+
+        // Draw object 1
+        ....
+
+        // Query current timestamp N
+        glQueryCounterANGLE(queries[N-1], GL_TIMESTAMP_ANGLE);
+
+        // Draw object N
+        ....
+
+        // Query current timestamp N+1
+        glQueryCounterANGLE(queries[N], GL_TIMESTAMP_ANGLE);
+
+        // Wait for all results to become available
+        while (!available) {
+            glGetQueryObjectivANGLE(queries[N], GL_QUERY_RESULT_AVAILABLE_ANGLE, &available);
+        }
+
+        for (i = 0; i < N; i++) {
+            // See how much time the rendering of object i took in nanoseconds.
+            glGetQueryObjectui64vANGLE(queries[i], GL_QUERY_RESULT_ANGLE, &timeStart);
+            glGetQueryObjectui64vANGLE(queries[i+1], GL_QUERY_RESULT_ANGLE, &timeEnd);
+            timeElapsed = timeEnd - timeStart;
+
+            // Do something useful with the time.  Note that care should be

+            AdjustObjectLODBasedOnDrawTime(i, timeElapsed);
+        }
+
+Issues from EXT_timer_query
+
+    (1) What time interval is being measured?
+
+    RESOLVED:  The timer starts when all commands prior to BeginQuery() have
+    been fully executed.  At that point, everything that should be drawn by
+    those commands has been written to the framebuffer.  The timer stops
+    when all commands prior to EndQuery() have been fully executed.
+
+    (2) What unit of time will time intervals be returned in?
+
+    RESOLVED:  Nanoseconds (10^-9 seconds).  This unit of measurement allows
+    for reasonably accurate timing of even small blocks of rendering
+    commands.  The granularity of the timer is implementation-dependent.  A
+    32-bit query counter can express intervals of up to approximately 4
+    seconds.
+
+    (3) What should be the minimum number of counter bits for timer queries?
+
+    RESOLVED:  30 bits, which will allow timing sections that take up to 1
+    second to render.
+
+    (4) How are counter results of more than 32 bits returned?
+
+    RESOLVED:  Via two new datatypes, int64ANGLE and uint64ANGLE, and their
+    corresponding GetQueryObject entry points.  These types hold integer
+    values and have a minimum bit width of 64.
+
+    (5) Should the extension measure total time elapsed between the full
+        completion of the BeginQuery and EndQuery commands, or just time
+        spent in the graphics library?
+
+    RESOLVED:  This extension will measure the total time elapsed between
+    the full completion of these commands.  Future extensions may implement
+    a query to determine time elapsed at different stages of the graphics
+    pipeline.
+
+    (6) If multiple query types are supported, can multiple query types be
+        active simultaneously?
+
+    RESOLVED:  Yes; an application may perform a timer query and another
+    type of query simultaneously.  An application can not perform multiple
+    timer queries or multiple queries of other types simultaneously.  An
+    application also can not use the same query object for another query
+    and a timer query simultaneously.
+
+    (7) Do query objects have a query type permanently associated with them?
+
+    RESOLVED:  No.  A single query object can be used to perform different
+    types of queries, but not at the same time.
+
+    Having a fixed type for each query object simplifies some aspects of the
+    implementation -- not having to deal with queries with different result
+    sizes, for example.  It would also mean that BeginQuery() with a query
+    object of the "wrong" type would result in an INVALID_OPERATION error.
+
+    UPDATE: This resolution was relevant for EXT_timer_query and OpenGL 2.0.
+    Since EXT_transform_feedback has since been incorporated into the core,
+    the resolution is that BeginQuery will generate error INVALID_OPERATION
+    if <id> represents a query object of a different type.
+
+    (8) How predictable/repeatable are the results returned by the timer
+        query?
+
+    RESOLVED:  In general, the amount of time needed to render the same
+    primitives should be fairly constant.  But there may be many other
+    system issues (e.g., context switching on the CPU and GPU, virtual
+    memory page faults, memory cache behavior on the CPU and GPU) that can
+    cause times to vary wildly.
+
+    Note that modern GPUs are generally highly pipelined, and may be
+    processing different primitives in different pipeline stages
+    simultaneously.  In this extension, the timers start and stop when the
+    BeginQuery/EndQuery commands reach the bottom of the rendering pipeline.
+    What that means is that by the time the timer starts, the GL driver on
+    the CPU may have started work on GL commands issued after BeginQuery,
+    and the higher pipeline stages (e.g., vertex transformation) may have
+    started as well.
+
+   (9) What should the new 64 bit integer type be called?
+
+    RESOLVED: The new types will be called GLint64ANGLE/GLuint64ANGLE.  The new
+    command suffixes will be i64 and ui64.  These names clearly convey the
+    minimum size of the types.  These types are similar to the C99 standard
+    type int_least64_t, but we use names similar to the C99 optional type
+    int64_t for simplicity.
+
+Issues from ARB_timer_query
+
+   (10) What about tile-based implementations? The effects of a command are
+        not complete until the frame is completely rendered. Timing recorded
+        before the frame is complete may not be what developers expect. Also
+        the amount of time needed to render the same primitives is not
+        consistent, which conflicts with issue (8) above. The time depends on
+        how early or late in the scene it is placed.
+
+    RESOLVED: The current language supports tile-based rendering okay as it
+    is written. Developers are warned that using timers on tile-based
+    implementation may not produce results they expect since rendering is not
+    done in a linear order. Timing results are calculated when the frame is
+    completed and may depend on how early or late in the scene it is placed.
+    
+   (11) Can the GL implementation use different clocks to implement the
+        TIME_ELAPSED and TIMESTAMP queries?
+
+   RESOLVED: Yes, the implemenation can use different internal clocks to
+   implement TIME_ELAPSED and TIMESTAMP. If different clocks are
+   used it is possible there is a slight discrepancy when comparing queries
+   made from TIME_ELAPSED and TIMESTAMP; they may have slight
+   differences when both are used to measure the same sequence. However, this
+   is unlikely to affect real applications since comparing the two queries is
+   not expected to be useful.
+
+Issues
+
+    (12) What should we call this extension?
+
+    RESOLVED: ANGLE_timer_query
+
+    (13) Why is this done as a separate extension instead of just supporting
+         ARB_timer_query?
+
+    ARB_timer_query is written against OpenGL 3.2, which includes a lot of
+    the required support for dealing with query objects. None of these
+    functions or tokens exist in OpenGL ES, and as such have to be added in
+    this specification.
+
+    (14) How does this extension differ from ARB_timer_query?
+
+    This extension contains most ARB_timer_query behavior unchanged as well
+    as a subset of the query support required to use it from the core
+    OpenGL 3.2 spec. It omits the glGetInteger(TIMESTAMP) functionality used to
+    query the current time on the GPU, but the behavior for all remaining
+    functionality taken from ARB_timer_query is the same.
+    
+    (15) Are query objects shareable between multiple contexts?
+
+    RESOLVED: No.  Query objects are lightweight and we normally share 
+    large data across contexts.  Also, being able to share query objects
+    across contexts is not particularly useful.  In order to do the async 
+    query across contexts, a query on one context would have to be finished 
+    before the other context could query it. 
+
+Revision History
+
+    Revision 1, 2011/04/28
+      - copied from revision 9 of ARB_timer_query and revision 7 of
+        ARB_occlusion_query
+      - removed language that was clearly not relevant to ES2
+      - rebased changes against the OpenGL ES 2.0 specification
