What I'm saying is the changelog should explain why would want to apply
the patch. What does the inversion mode do? Is it inverting the color
or flipping something upside down?
Probably if I had a background in graphics I would know what "Enable
inversion mode" means... But three words is not a proper and complete
commit message normally.
