Mask delegate works on the image alpha, not gray scale bands. #13

If you create a mask layer as a black and white image, it does not recognise it as a mask.

The issue is that the mask reader delegate takes the alpha channel from the mask tiles, and uses it as the alpha.

It would be good to be able to use greyscale images to define a mask (similar to GIMP etc.)
