How do antialiased polygons and circles in Max2D?

I can get antialiased lines with

SetGraphicsDriver GLMax2DDriver()
Graphics 640, 480, 0
SetColor 100,100,100
glEnable(GL_POLYGON_SMOOTH)
glEnable(GL_LINE_SMOOTH)
SetBlend ALPHABLEND
DrawLine 0, 0, 639, 479
Flip
WaitKey()
End

But I cant get antialiased polygons or ovals.

If somebody knows how to get antialiased polygons or ovals in Max2D please help me :/

Try drawing antialiased lines along your polygon edges.

Do you need to enable shading rather than flat?
