So there is a common pattern (hence a common fix?). Overall, it seems
that stock icons (i.e not Inkscape provided ones) scale, but Inkscape
icons do not scale. I understand this since Inkscape icons used to be
designed and rendered in a different way. However:
- I thought that recent changes to the icon handling would make
Inkscape icons behave as the rest (this was tested with rev 21339 and
I haven't seen any icon related changes in the svn log since, and with
no custom configuration in .config/Inkscape)
- even if they do not behave as the rest, they should at least display
at their maximum size when the GTK size it set higher that it (32 and
48).
Thanks in advance for any information on all this.
