mesa/965: add support for GL_EXT_framebuffer_sRGB (v2)
This adds i965 support for GL_EXT_framebuffer_sRGB, it introduces a new constant to say that the driver can support sRGB enabled FBOs since enabling the extension doesn't mean the driver can actually support sRGB. Also adds the suggested state flush in the core code suggested by Brian. fix the ARB_fbo color encoding. Signed-off-by: Dave Airlie <airlied@redhat.com>
