A GdkGC can be used with any drawable with the same depth and
GdkScreen as the one for which is was created.
However, drawing onto a drawable that interprets colors differently
is likely not useful, so you really need the two drawables to have
the same GdkColormap.

P.S.:
G_INLINE isn't used like that.
There is no significant value to G_UNLIKELY in this type of code;
it reduces the readability of your code for a very tiny
performance improvement.
