sounds good :-) I just tried to try imlib... ;) but the program in TST
did only segfault after bringing up a window for shorter than half a second :(

I want to draw a transparent pixmap on an area with a background which
should partly be still visible... for example a planet on a background,
and in the corners of the pixmap should be still the background...

I don't want to use widgets because it could get time and resource
consuming (like gtklist) as there might be hundreds of pixmaps...
every gtkpixmap would have to be destroyed and recreated when the starchart
is rotated

I just saw libwraster... i'll try that one till gdk_imlib is released...
