Perhaps virglrenderer should not expose e.g. PIPE_DISPLAY_TARGET for
srgb if it doesn't support EXT_sRGB_write_control. The extensions
exposed should be a function of what the driver supports. What is so
special about EXT_sRGB_write_control that each driver must determine
individually for just that one extension that can't be derived from
the supported formats and bind flags?
