* Adds support for EXT_framebuffer_multisamplegman@chromium.org2010-08-233-0/+57

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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?

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.

Not the munged shader sent to GL. * Another issue that came up is that client side validation is needed to ensure that the client side GLES2Implementation does not generate bad commands. For example, calling glUniform1iv with a negative count would generate a bad command. The service side would see that and think the program was malicious and stop processing commands. So, that means I had to add some client side validation and wrap glGetError on the client side so I can synthisize GL errors there. TEST=lots of unit tests.
