Modification History

Written by David Fanning, May 25, 2007 based on code named BitmapForButtonText supplied to the IDL
newsgroup by Dick Jackson: http://www.idlcoyote.com/tip_examples/bitmapforbuttontext.pro.
Fixed a problem with foreground and background colors that caused them to work correctly only
when color decomposition is on--as it should be :-). 6 May 2009.
