You're right, but there is still yet another problem with transparent
pixmaps... :(
If the underlying background is another pixmap, things are not handled
properly. Maybe I'm just not sure how to make it work properly, but I
don't see how. (I even tried using gtk_widget_set_style to make sure
that the pixmap was getting the same style as the button, which does
have the proper pixmap background, but that didn't work)
Personally, I don't think it's much of a problem... I don't care for
pixmap backgrounds anyway, but I'm sure it will have ramifications on
gzilla and the gtk-based-rxvt-replacement-with-pixmap-backrounds. (you
know -someone- is going to do it, no matter how sickening it might be :)
