Sure the amount of data stays the same - however for (most modern)
video drivers which place their pixmaps in vram it does make a
difference.The whole situation is quite ugly :-/

Hmm, I guess the best thing would be to get GTK's broken theme API
right, to draw on a cairo-context instead of a GdkDrawalbe.
I submited patches for rfc some time ago, but nobody really looked at
it. To me it seems GTK is quite dead.
When I brought that topic up again, it was mentioned that the work is
obsolete because GTK+3 will have an all new-any-shiny theming API
which will be perfect in any aspect.
However they are talking about GTK+3 for about 2,5 years now, with no outcome.
Hmm, I am starting to get personal again ;)
