    Alternate CopyPixels path based on get/put_tile().
    
    For some drivers (like Xlib) it's not possible to treat the front/back color
    buffers as pipe_regions.  So pipe->region_copy() won't work.  Added a new
    state tracker field indicating if we can use regions for colorbuffer accesses.
    This should probably be re-considered someday...
