		float	radius,
		u32	clr0,
		u32	clr1,
		u32	clr2,
		u32	clr3
	)

inlinestatic

Draws a circle (an ellipse with identical width and height) using the GPU.

Parameters

[in]	x	X coordinate of the center of the circle
[in]	y	Y coordinate of the center of the circle
[in]	z	Z coordinate (depth value) to draw the ellipse with
[in]	radius	Radius of the circle
[in]	clr0	32-bit RGBA color of the top-left corner of the ellipse
[in]	clr1	32-bit RGBA color of the top-right corner of the ellipse
[in]	clr2	32-bit RGBA color of the bottom-left corner of the ellipse
[in]	clr3	32-bit RGBA color of the bottom-right corner of the ellipse

Note: Switching to and from "circle mode" internally requires an expensive state change. As such, the recommended usage of this feature is to draw all non-circular objects first, then draw all circular objects.
