* gtk/gtkcolorsel.c (gtk_color_selection_dialog_new):
Pushing and popping the visual/cmap in the init()
function does no good, because the window itself needs
to be create with that visual/cmap.
So do it in the new() function instead.
This will require people doing gtk_widget_new() to do
the push/pop themselves, but I don't see any way around
it other than digging in and tweaking the window
widget's colormap and visual ourselves, which
is highly non-kosher, but would be safe...
