// Manages color allocation so as to allow any combination of
// foreground/background colors to be used. If there aren't enough
// color pairs available to handle all color combinations, this will
// act as though no colors are available. NOTE: colors whose
// foreground and background are the same will be reduced to an
// arbitrary color of that background; it is expected that the caller
// will apply A_INVIS to such colors. This is done to conserve color
// pairs so as to allow the use of the 'default' color.

* mix foreground and background colors independently of one another.
* Normally colors are accessed through the style system (see
