For some transforms one way makes sense for some the other makes
sense. I would suggest that if you are doing the filter in an
untransformed coordinate system and later transforming that to the
device, you should use a fairly high quality implementation of affine
transform to do the mapping, you should also take care to scale the
untransformed coordinate system properly.
