* gdk/gdkdraw.c: Added a check on the colormap depth to
gdk_drawable_set_colormap()
* gdk/x11/gdkimage-x11.c: combination of Mathias Hasselmann's
patch to fix colorsel and my patch to fix gdk_drawable_get_image()
for pixmaps without visuals (more specifically, bitmaps)
* gdk/x11/gdkpixmap-x11.c: Fixed gdk_pixmap_new() so it
doesn't set a colormap with the wrong depth
