 This is the ANGLE project, from http://code.google.com/p/angleproject/.
 
-Current revision: r515
+Current revision: r550
 
-Local patches:
+Applied local patches:
     angle-shared.patch - add declspec dllexport/dllimport support on win32
 
     angle-fixes.patch - fix angle issues 51 & 52
 
     angle-nspr-misc.patch - don't bother with ANGLE_OS detection with NSPR
 
-    angle-pbuffers.patch - add pbuffer support to ANGLE, and d3d texture handle query (angle issue 91)
-
 == 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.
