I didn't think about that. Indeed, it should work (did somebody try?),
but only if everything is axis aligned. For simple shear, it would not work.
Perhaps something similar can be done with Hsize after last changes :
tempHSize = Hsize
trsf = identity
Hsize = tempHSize

This means one has to undo manualy what "trsf=" is doing silently. Not
really intuitive...
