* Add way to create a texture in parent's context and copy into itjamesr@chromium.org2010-08-281-0/+14
| | | | | | | | | | | | | | | | | | | | | | For canvas we need a way to create multiple offscreen render targets within the same OpenGL context and expose them all to the compositor, which exists as a parent context. ggl currently provides a single framebuffer and texture pair per offscreen context and implements swapBuffers() to copy to the parent texture. This generalizes that to let clients create as many parent textures as necessary and do the equivalent of swapBuffers() for each without the service side needing to keep track of the mapping. We'll want to change this in the future when we start using glBlitFramebuffer to support multisampling. I think in that world we'll need a way to bind a texture in the parent's context to the DRAW_FRAMEBUFFER context. For now, I think this is OK.

| | | | | | | | | | | | | | | | | This is only the internal command buffer implementation. Connecting these functions publicly to PPAPI or whatever will happen separate from this CL. It's not clear to me where to put GL_READ_ONLY and GL_WRITE_ONLY Probably the same place we expose these 2 functions to the public.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | to more than one target. We had originally decided that this would be an disallowed. glBindBuffer(GL_ARRAY_BUFFER, some_buffer_id); glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, some_buffer_id); Unfortunately the GLES2 conformance tests require this behavior. This CL makes this behavior possible but it has to be turned on because it means all buffers have to have CPU side backing (not just ELEMENT_ARRAY_BUFFERs) and it means a slowdown for dynamic vertex related stuff like skinning because an extra copy has to be made every time they are updated. So, by default it will be off but we'll come up with some way to turn it on. Al's suggestion is to use eglCreateContext with a custom intialization attribute. My #1 question: What about the name of the command, the name of the constant and the filename the constant is in. Any thoughts?
