Bug 1646835 - move SWGL context creation into specific SWGL RenderCompositors. r?jrmuizel Summary: Currently RendererOGL has mixed-in details of SWGL context creation which becomes messy and slightly unanticipated based on the nomenclature and structure of RendererOGL. Based on other work in bug 1646835, it becomes more natural to move this context creation into the specific SWGL RenderCompositors so that RendererOGL can be agnostic to any SWGL details.

Bug 1646835 - refactor RenderCompositorOGL into RenderCompositorNative. r?mstange Summary: RenderCompositorOGL currently has many responsibilities including supporting OpenGL compositor for Linux, whole-window compositing for Mac NativeLayerCA, and per-cache-tile compositing for Mac NativeLayerCA. With the addition of support for SWGL, this becomes even further complicated. It becomes advantageous to separate out RenderCompositorOGL specifically as only the basic OpenGL compositing case, as that naturally yields a simple and isolated RenderCompositor. What is left over becomes RenderCompositorNative, a basis for implementing NativeLayer-based RenderCompositors. To cleanly isolate state and details of when HW compositing or SW compositing is being used, these are further split off into RCNativeOGL and RCNativeSWGL versions that deal with specific isolated details of OpenGL and SWGL respectively. RCNativeOGL deals with just setting up OpenGL FBOs for NativeLayers. RCNativeSWGL's new task is just to deal mapping NativeLayers and providing SWGL FBOs for them without involving OpenGL.

Bug 1646835 - add MapTile/UnmapTile hooks to the WR compositor. r?mstange,gw Summary: RenderCompositors for SWGL that wish to provide accelerated compositing need to subvert the existing Bind/Unbind hooks in the WR compositor. These compositors need to keep track of their HW tiles without actually binding an OpenGL FBO for WR to render picture cache tiles. SWGL needs to intervene and get a backing buffer for tile from the RenderCompositor so that it can create a SWGL FBO for WR to render the picture cache tile to. To that end, this adds MapTile/UnmapTile as a replacement for Bind/Unbind for those scenarios. This is done in a way that it affects only the WrCompositor of webrender_bindings without actually altering WR's Compositor interface. This is beneficial because WR does not have to understand the details of SWGL integration and also so as not to complicate other users of WR such as Servo who are not currently utilizing SWGL at all. RenderCompositorOGL is initially modified to use these hooks in this patch. It later became more convenient to restructure that in a follow-up patch.

Bug 1646835 - implement basic SWGL compositor. r?jrmuizel Summary: This is a first implementation of a software-only SWGL RenderCompositor that relies on the existing widget hooks for Basic compositing. It attempts to lock the widget and get a DT whose underlying data it can supply directly to SWGL to composite to. Critically, it does not rely on OpenGL or any other form of HW accel to function. The interface between the RenderCompositor and SWGL will be further refined in follow-up patches.

Bug 1646835 - allow specifying backing data and stride for SWGL default framebuffer. r?jimb Summary: For performance reasons in SWGL software compositors. to avoid unnecessary full-screen copies of the framembuffer, we need to allow those compositors to map their underlying widget surfaces and pass that buffer to SWGL so that they can be directly rendered to. That also requires supporting custom strides, as we can't always enforce the particular layout of the buffers handed off to us. To that end, InitDefaultFramebuffer is generalized to take such information and then many places where we rely on a specific hard-coded SWGL-calculated stride have been altered to deal with a caller-supplied stride.
