We use the png_set_expand() function to force the PNG library to decode to 24 bits, which is the correct thing to do in this case.
Because we decode to 24 bits, then we set the image up as a 24 bit image (with the pitch set accordingly). I would assume that GrDrawImage() uses some of the values from the image struture without properly adjusting them for the real depth of the window first.
