Actually thi is a very good idea!
I'm going to try it right away!

I'd suggest drawing from the edge to the center.
That is, determine each pixel that makes up the
edge of the arc, then draw from it to the center.
If you draw from the center, I am imagining some
sort of code that steps through degrees, or fractions
of degrees, and depending upon the diameter of the
circle of which the wedge is a part, any fraction
of a degree you use may still result in some
non-filled pixels towards the edge of the wedge.
