 * Notes on Colors:
 *
 *   1) On a monochrome (or "fake-monochrome") display, all colors
 *   will be "cast" to "fg," except for the bg color, which is,
 *   obviously, cast to "bg".  Thus, one can ignore this setting.
 *
 *   2) Because of the inner functioning of the color allocation
 *   routines, colors may be specified as (a) a typical color name,
 *   (b) a hexidecimal color specification (preceded by a pound sign),
 *   or (c) by strings such as "fg", "bg", "zg".
 *
 *   3) Due to the workings of the init routines, many colors
 *   may also be dealt with by their actual pixel values.  Note that
 *   the pixel with all bits set is "zg = (1<<metadpy->depth)-1", which
 *   is not necessarily either black or white.
