When I wrote the image support for Windows, I tested a wide range of PNG
test images. PNG support appears to be broken in the Windows port now
though, as all images with transparency or alpha channels are appearing
inverted. This may be something to do with the bug that YAMAMOTO
Mitsuharu just pointed out.

I see the problem. You don't want to have to know in advance whether the
image has transparency or not.
What about: if the image already has a mask (due to the fact it is a
transparent image), any heuristic mask property should be ignored. Would
that be better than relying on corner pixels being transparent?
