Your mask bitmaps seem to be not 1 bit depth. AFAIK you have to use
CreateBitmap instead of CreateCompatibleBitmap for them (and set the
depth to 1 bit). 
You can look at the implementation of DrawIcon (gdi32) in wine.
It handles a similar problem as the stuff in gui-win32/graphics.c
(drawing bitmaps with a "mask")
