meta: Add a meta implementation of GL_ARB_clear_texture
Adds an implementation of the ClearTexSubImage driver entry point that tries
to set up an FBO to render to the texture and then calls glClearBuffer with a
scissor to perform the actual clear. If an FBO can't be created for the
texture then it will fall back to using _mesa_store_ClearTexSubImage.
When used in combination with _mesa_store_ClearTexSubImage this should provide
an implementation that works for all DRI-based drivers. However as this has
only been tested with the i965 driver it is currently only enabled there.
v2: Only enable the extension for the i965 driver instead of all DRI drivers.
Remove an unnecessary goto. Don't require GL_ARB_framebuffer_object. Add
some more comments.
v3: Use glClearBuffer* to avoid having to modify glClearColor and friends.
Handle sRGB textures. Explicitly disable dithering.
