* Added command buffer implementation of WebGL which runs in the sandbox.kbr@google.com2010-03-271-5/+68
| | | | | | | | | | | | | | | | | | | | | | Added synchronous initialization of the channel to the GPU process, needed to obey WebGL startup semantics. There are problems with this on the Windows platform which will be addressed via refactoring in the GpuProcessHost in a subsequent CL. Implemented offscreen rendering code path in GGL / GLES2CmdDecoder for Mac OS X. This new code path is not yet complete for all platforms and is still being stress tested. The previous in-process WebGL implementation is currently used when the sandbox is disabled; it will be removed in a subsequent CL. A one-line code change in WebKit is needed after this CL lands to enable the new code path.

One issue that has come up is we need to make sure that no GLES2 client call can crash the GPU process. In other words, the GLES2Implementation must never generate a command the service side will see as malicious. For example: glTexImage2d(..width = 0x7fffffff, height = 0x7fffffff) should return an gl error rather than pass it through to the service side which will currently return a parse error and stop the GPU process. It does make me wonder if the service side should return GL errors for more things rather than parse errors.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | side can know if it should or should not copy the results. This is the way the spec is. If ReadPixels fails it's not supposed to modify client side memory. Unfortunately that makes it slow because it stalls the GPU pipeline 3 times. The service side has to call glGetError to save up any current errors. That's one stall. Then it calls ReadPixels, another stall, finally calls glGetError a 3rd time to see if ReadPixels succeeded so that it can tell the client side implementation of ReadPixels whether or not to copy memory. We could decide to change the behavior of ReadPixels so it always copies. That wouldn't be spec complient but suspect most developers never expect it to fail and don't count on it not always writing to their memory.

While not optimal, it works and can be optimized later, after the new GPU process work is completed. This CL also enables stencil buffer support on the Mac. All the Pepper3D demos run on the Mac with these changes. BUG=none TEST=3D rendering unit tests.
