Hmm, maybe it's just that range is too small. If I do -from -10 -10 -to 10 10 it works.

There was actually a bug with using from/to. I was sure I pushed a fix for this the other day, but I can't see it in the github commit history. However looking at the source of worldloader.cpp at github there are the "< 0" checks in calcBitmapOverdraw() that fixed it.
Do you have them in your local copy?
Anyways, since I'm reverting parts of the overdraw/cropping stuff, it should be fixed for sure in the next version.
