/*
 * Caveats: monochrome and colour bitmaps are drawn differently. When
 * a monochrome bitmap is pressed down, it is drawn with the BITMAP given
 * in the TOOLDISPLAYINFO structure as a background brush. If you are
 * using colour bitmaps or don't care, just fill in 0 for the background.
 *  However, I believe monochrome bitmaps look much better, so try and
 * use those. For am example, see the VI toolbar in the default configuration.
 * Half of the bitmaps are colour, and the other half are monochrome (accident?).
