[Sugar-devel] SVG performance

[Walter Bender]

It was easy enough to add the extra couple of lines to see if the
cache already exists. TA launches blazingly fast (after the very first
time you use it). But I do have two concerns: (1) now that TA caches
its images, which are language-specific, how do I catch a change in
language and then generate a new cache? I suppose I could make all the
filenames include a language-specific suffix of some sort, but that
seems kludgy. (2) When I update the activity, how will I know to
update the cached images?
