it good, yeah, maybe i don't like really much changing d->prefix generating 
the thing and then again but making generatebackground aware of the mask it's 
a bit complicated, so i think it's ok.
about deleting the frame after generating i suppose yes, since the bitmap is 
already cached..
i think i will need this mask also for a new theme element, i think it would 
make sense to make it a private function like alphaChannel() or something like 
this
