This is somewhat tricky, because in MSL this value is obtained through a function, `get_sample_position()`. Since the call expression is an rvalue, it can't be passed by reference, so functions get a copy instead. This was the last piece preventing us from turning on sample-rate shading support in MoltenVK.
