Dan,
I'm assuming you mean using the "FAST" render mode? The cairo
rendering seems to work fine for me with top-cop.gbx.
The short answer is: it will take too much time to get the GDK stuff
to render translations/mirrors/etc 100% correct. We manually have to
figure out the shape of all the shapes in GDK, and it simply would take
too much boilerplate logic for it to be worth it when we have to take
into account all possible mirror/rotate/scaling options. One idea would
be to display a warning dialog when the user first modifies a layer to
alert the user that FAST will not render 100% correctly. This would
hopefully make sure the user understood this.
Other thoughts?
