Reading back my previous comments I notice that I've been quite wordy and
maybe I didn't do a great job explaining my point.
I created some visual tests showing how blender deals (in my oppinion
incorrectly) with associated files from other applications and how
pre-divide creates proper sRGB associated files for compositing in
non-linear space.
I used GIMP for that, but this can be checked even using Blender's VSE.
