(Speaking in 2.6:)

My first attempt at Translating a series of FillRects to simulate
packets moving through a queue resulted in a rather disappointing
performance on my Sparc 2.  I've got to speed things up quite a bit,
and I'm wondering whether a series of Stencils (Bitmaps?) would be any
faster.  (Actually, my guess is it's not the Translating, but the
Updating done by my damage object which takes up so much time).  Does
anybody have an idea as to whether a Stencil can be redrawn faster
than a FillRect?

Thanks,
