raster image works on Linux, busted on Windows

[Charles McCreary]

I've been working with/on thuban in Linux and all is well. When I built 
on Windows, I ran into a problem with raster images. I previously posted 
  three messages about the problem but I used a non-list-member email so 
they are awaiting moderator approval, please disregard.

The raster image shows up masked, as it turns out. The default masktype 
is MASK_BIT (layer.py - RasterLayer.__init__). If I change the masktype 
to none or alpha, the raster is displayed properly.

Why does MASK_BIT work differently on linux and windows?
