You can only create pixmaps that your X display supports, so a 16-bit
display won't support 24-bit pixmaps.

Perhaps you are trying to use pixmaps as a client-side data structure
instead of as a way to display your image data; you might consider using
GdkRGB (gdk/gdkrgb.h) to store your 24-bit data and use GdkPixmap only to
render the data on the screen.
