Yup, it never did it correctly. Neither of 'canvas-scaling'
(per Simon's comments) nor 'viewport-scaling' is really a substitute
for the other. But for completeness and consistency, the api should
allow you to obtain (correct) viewport-scaling via suitably 'scaling'
object properties -- and if the canvas consists only of image objs
say, then this should agree with canvas-scaling.
Right now this lacks only 'border-fill' and 'text-scaling'
funcs -- and correct implementations thereof (angle related stuff
just needs the user to modify things accordingly. I should've
done it before when viewport-scaling was still around, but just
never got around to it).
The text related scaling implementation should use freetype
internally to get this 'right' as much as possible - that's likely
to be a pain in the font-butt, but should be doable. Doesn't seem
like a pressing issue to me though to get this 'fixed' right away,
for some reason.
The border related implementation is easier, very easy
really for the software engines, but for xrender and gl it's
going to be a pita to get this working efficiently (it's a pita
already).
Actually, now that I think about it.. I'd have to re-write
all the span-based software scaling funcs that I just did..
Ummmmmm...... absolute border sizing is also starting to
sound like less of an issue to me, for some reason.
