* Rename async upload/readback queries to avoid mix-upssievers@chromium.org2013-08-271-4/+4

| | | | | | | | | | | | | | | | | | | | | | | Third try for getting asynchrous readpixels to work everywhere. This is identical to: https://codereview.chromium.org/16831004/, but with the following fixes: OutOfProcessPPAPITests.Graphics3D (removed a check in query_tracker.cc) GLReadbackTest.ReadPixelsWithPBO (removed, no longer a valid test) GLReadbackTest.ReadPixelsWithPBOAndQuery (now uses the correct query) And, new in this CL: Disable asynchronous readpixels on macosx prior to 10.8, as it would seem that the GL_ARB_fence extension doesn't seem to work on any driver, and there are crashes in readpixel itself on intel drivers. The original CL only disabled the async readpixels path for intel drivers.

| | | | | | | | | | This changes the semantics of ProduceTexture to not replacing the current texture by a dud, but instead keeping the existing one, that it also puts into the mailbox. It changes the semantics of ConsumeTexture to deleting the current texture, and replacing it by the mailbox contents (without taking it out of the mailbox). The texture becomes shared. The mailbox is now effectively a weak pointer onto the texture.

| | | | | | | | | | | | | | | | | | | | | | | | | This version corrects the problem that caussed the revert of the above issue. The shaders used by the extension were specifying a precision, which is not supported on desktop GL. The shaders now conditionally specify the precision. ------------------------------------------------------ Introduction of CHROMIUM_copy_texture extension that respects pixel-store semantics, and allows copying of BGRA textures. OpenGL ES does not natively allow for copying textures with a BGRA format. The EXT_texture_format_BGRA8888 extension does not specify support for glCopyTexImage calls on these textures. This extension provides a routine to perform texture copies to/from BGRA-backed textures that also respects the following CHROMIUM pixel storage modifiers: UNPACK_FLIP_Y_CHROMIUM UNPACK_PREMULTIPLY_ALPHA_CHROMIUM This extension will be useful for the following purposes: - Copying accelerated Canvas2D contents to WebGL textures without a software readback. (And potentially the same for video-webgl texture copies.) - Copying Canvas2D contents to the compositor backing store.

| | | | | | | | | | | | | | | | | | | | | | textures, and added Mac OS X-specific extension for binding IOSurfaces to textures. This is infrastructure work for rendering Core Animation plugins via Chrome's compositor. Refactored the texture initialization in the command buffer and associated unit tests. Added unit tests for rectangular textures. These changes will be hooked up in a subsequent CL. They were split off for easier review. There are ongoing discussions about unifying the various mechanisms for sharing textures across processes, but it's been agreed that those should not block this work.
