getmcolor()

[David R. Blythe]

getmcolor() doesn't appear to work in RGB mode (it returns 0's).
I guess this shouldn't come as a surprise, but its not documented as working
only in cmode, and mapcolor() does seem to work in RGB mode.  The reasons
for trying to use it in RGB mode are a bit obscure and its easy to work
around, but someone may want to fix it (if its fixable). 4D/70GT running
3.3.1.
