Thanks.

I keep running into little problems with Corel Painter 12. Working with layer masks is so buggy that it's basically impossible to use any masking features beyond the absolute basics. For a 300€ software - which used to cost 1k€ - I really, really expect more. Hell, Gimp can handle them better. This may prove to be a showstopper; I edited the coastlines so now I need to to create a new mask for the existing layer. I think I know how that would work, except every time I switch masks and try to edit them, Painter 12 starts dying a disk access death.
