Suggestion: Rather than perform each new rotation on the graphic's current
set of points, why not keep a running total of the accumulated angle, and
rotate the *original* set of points *every time*? If you rotate the current
set of points, you run the risk of accumulating roundoff error and such; if
you always rotate the original set of points, you never have more than one
rotation's-worth of error to worry about.
Hope this helps...
