I've reviewed those now.

This seems very much like a 'how could that ever have been the right
idea' kind of change to me -- setting the pointer position for a device
shouldn't ever have depended on whether that device was delivering core
events or not. In any case, the change seems obviously correct to me

However, this still looks very fragile -- fill_pointer_events does not
check the return value from miPointerSetPosition, which is still allowed
to return NULL in some cases. I don't think any of those are valid
though, so I'd suggest that either miPointerSetPosition or
positionSprite throw a fatal error instead of blindly wandering into a
segfault.
