For the purpose of incrementally intergration of existing intel driver, for the GC operations we may don't want to use glamor's internal fallback which is in general much slower than the implementation in intel driver. If the parameter "fallback" is false when call the glamor_fillspans, then if glamor found it can't accelerate it then it will just return a FALSE rather than fallback to a slow path.
