Wayne, if you are dealing directly with the color manager without using
the palette manager, then you should be able to XOR by yourself.  Now,
if you are using the Palette manager, specify the color entry usage for
all the entries as "pmExplicit + pmTolerant" and set the tolerance to
zero.  This instruct the palette manager to use the colors exactly as
they were defined (pmTolerant == 0), and exactly in the entry position
they were defined (pmExplicit).  You can do these when creating the
palette, or by using SetEntryUsage over the entries you want control.
Hope this help. -Frankie-
