Draw filled circle on the ground

[gajop]

Using DrawGroundCircle creates an empty circle on the ground, respecting height map. Using DrawGroundQuad creates a filled rectangle on the ground, respecting height map.

Is there any way to have DrawGroundCircle create a filled circle, much like it does while you're holding and dragging reclaim/attack/repair?
