Aha!  *NOW* i understand why JSUI is slow.  ;-)
It has nothing to do with the FSAA per-say.. this software-based
rendering is of course going to be slow.  Surely it might be
eventually possible to drop-in a more efficient renderer that takes
advantage of the operating system facilities for OpenGL?  (Maybe this
is planned, sorry I haven't read about the upcoming version yet..)

By the way I don't share Zola's opinion here.  I think JavaScript is
actually quite a decent language.  As for speed of execution, I pretty
much always expect interpreted languages to be slow and never expect
to use them in time-critical tasks.  This is what C is for.

I never did understand why the JSUI stuff seemed slower than need be,
but I didn't realized it was completely software rendered... (thus..
defeating the purpose of using OpenGL??  Though I'm sure it made it
easier to implement.)
