DrawOval outline

Like in B3D, how can I draw a oval outlined?

Drawoval( x, y, w, h, fill? )

I need it to work on both directx and opengl, any ideas?

Here is an unfilled ellipse routine:

You can use whatever you like to plot the points around the ellipse, and this code uses Max2D Plot so it will work with GL or DX.
