Issue of gdx_colormap_get() is tracked in:

The first idea about a replacement I had was:

 GdkColormap *gdk_x11_colormap_foreign_new (Display *display,
                                            Visual   visual, 
                                            Colormap colormap);

Why would you want gdk_colormap_sync(), gdk_colormap_add()
to be exported?

Do people actually use non-true-color visuals with 3D applications
(except on obsolete SGI hardware...) ?
