for some reason I am confused. (again!) There is A as ARGB and there is a as alpha!


so looking at link provided here 



it seems divide provided as operation only on color channels? And what we do with alpha in this and similar cases?

or may be I read wrong source again ....



at some point GIMP also has layer math problem, see


namely different visual results in different versions and then on top of this question about old project files ....




some more discussion about blend modes
