I've been keeping watch on this group for sometime and although I've seend
requests for circle/ellipse/arc functions, I was wondering if anyone had
an algorithm/source/pseudo-code for a filled-arc function.  I am currently
using a filled arc function which simply draws a line from the center point
to each point on the curve.  The problem with this is that in a large
arc, you end up with some gaps inside the arc.  I alleviate this problem
with a line function that draws a line 3 pixels wide instead of just one
but unfortunately this function is horrendously slow.  

Is there a better method for filling an arc or should I just make an
effort and improve on the wide line function?  It seems to me that
there would be a better way to do this but I haven't the faintest idea
how.

Thanks.
