Maybe I'll adress this in my next Glib patch.

Yeah. If you wouldn't mind I could even commit these changes to cvs myself.
I've got an account - mainly for my win32 Dia port. (It would be my first
direct Gtk+ commit, but there are already some patches from me in the Win32
And I'm trying to make recent Gtk+ working again on Win32, which simply
requires to build gdk-pixbuf first.

although IHMO the much cleaner way to generalize would be in the library.
Instead of just another implementation of application specific XPM code ...

Ok. Forget about the gdk_pixbuf::xpm_image_save.

Do you really think all the Gtk users will convert their XPMs to inlined PNGs?
(Which forces just another tool dependency.)
Are there plans to drop the XPM support in Gdk ?
Thanks again for the even faster response,
