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?
