If I read the patch correctly, you now auto-scale inside image.c,
which shouldn't change anything when not using :scale. What's the
effect when code passes in eg :scale 2? Autoscaling + frame scaling,
so for a frame where scale == 2 we get * 4? I guess that would be
sensible, but weʼd need to explain it clearly. [1]

I think Lars did the autoscaling work. If things continue to work as
before for the normal case, and we explain the interaction between
:scale and frame scale I have no objections.

Footnotes:
[1] And it would get people out of the "1 physical display pixel == 1
logical display pixel" mindset that needed to be fixed in so many
places in the X backend.
