However, this copy can only work if the canvas backing is an RGBA texture and will fail for BGRA (the BGRA extension doesn't support glCopyTexImage2D). We need an alternative mechanism to do the copy either by explicitly drawing a textured quad onto the bound fbo or using the command buffer extension that twiz@ is working on. 874719 1 schenney 2013-04-12 07:42:46 -0700 https://code.google.com/p/chromium/issues/detail?id=230825
