That's actually interesting (and afaik undocumented :o)

Is it correct to say that line-scaling only kicks in with proportional scaling, either
via corner-handles, or when entering values into the size boxes (with closed padlock)?

Here's btw. how this stuff looks in Illustrator.
One may simply let the Line width grow towards the inner and everything remains on full pixels, in conjunction with pixel-snap.

PS: Hit the allowed attachment size with a gif of just a bit over 100kb btw.
Maybe one could raise those values a bit in 2016 ;o)
