Double drawing and proper number of verts #767

Closed Noofbiz closed 3 years ago

Noofbiz commented 3 years ago

I was counting the vertex that sets it to the center as a vertex that draws the circle, which led to an off-by-one offset in the circle. This caused the angles to be a little smaller than they should've been when using Circle.Arc, as well as double drawing of some triangles when the transparency was set to something other than 1 or 0.

Fixes for #766
