The GL framebuffer driver now makes sure to bind the framebuffer before counting the number of bits. Previously it would just query the number of bits for whatever framebuffer happened to be used last. In addition the virtual for querying the framebuffer bits has been modified to take a pointer to a structure instead of a separate pointer to each component. This should make it slightly more efficient and easier to maintain. Reviewed-by: Robert Bragg <robert@linux.intel.com> (cherry picked from commit e9c58b2ba23a7cebcd4e633ea7c3191f02056fb5)
