Taken from PalmOS Reference documentation, about WinPaintBitmap function :
"If the bitmap has multiple depths (is a bitmap family), the closest match
less than or equal to the current draw window depth is used. If such a bitmap
does not exist, the bitmap with the closest match greater than the draw
window depth is used."

You can aso test grayscale mode ( assumed you have at least Palm OS 3.5 ) on
a color device, by using WinScreenMode to specify the depth you want.
