i think this is the source of my confusion about global versus local
colormaps.
program A has a colormap of 256 colors. program B also has its own colormap
of 256 colors.
when a program uses its own colormap, it sounds like you're saying that
colormap replaces the global colormap(?) everyone else's colormap (?)
when the application has focus.
so there can only be a single active colormap at a time? the one whose
application currently has focus?
is that approximately what's going on?
