I checked and the behavior change seems to affect all .png files 
regardless of origin or what program generated them. I didn't check .jpg 
or other formats.

Any .png should therefore be substitutable for any other in checking this 
(except that the createCompatibleDestImage issue won't be detectable if 
it's a blank black .png).
