Re: Font chooser GtkAction migration

Is it possible for Inkscape to store the font previews in a file instead of
having to re-draw them all each time Inkscape is re-opened (and the font
dialog clicked on).
The reason is if you have a large number of fonts on the system, it takes a
very long time for Inkscape to re-draw them all, and in the meantime the
user can do nothing but wait (nothing else can be done in Inkscape until
all the previews are complete).

Ideally, Inkscape would only re-draw these previews when fonts are added or
updated, and even more ideally, NOT at the time when the user opens the
drop-down font chooser. Seems like something which could be checked when
Inkscape starts up?
Thanks for looking at it, Alex!
