Warning
gdk_gc_get_colormap has been deprecated since version 2.22 and should not be used in newly-written code. There is no replacement. Cairo handles colormaps
automatically, so there is no need to care about them.
Retrieves the colormap for a given GC, if it exists.
A GC will have a colormap if the drawable for which it was created
has a colormap, or if a colormap was set explicitely with
gdk_gc_set_colormap.
