Thanks for your reply. I'll submit the radar later today.
I'm still curious about elliptical paths and 360 degree arcs. Do
they always start/end on horizontals, or is there something that I'm
overlooking to have the path start at an arbitrary point?
Sorry, I'm not exactly sure how those functions work. If you want
complete control over the created path you can use the primitive
operations: CGPathMoveToPoint, CGPathAddLineToPoint,
CGPathAddCurveToPoint, CGPathAddQuadCurveToPoint and
CGPathCloseSubpath. Everything else will be decomposed into some list
of those. You can also use the CGPathApply function to inspect what
primitives your paths actually consist of.
