[in]	y0	Y coordinate of pt0.
[in]	c0	Color value of pt0.
[in]	tu0	Texture translation of pt0.
[in]	tv0	Texture translation of pt0.
[in]	x1	X coordinate of pt1.
[in]	y1	Y coordinate of pt1.
[in]	c1	Color value of pt1.
[in]	tu1	Texture translation of pt1.
[in]	tv1	Texture translation of pt1.
[in]	x2	X coordinate of pt2.
[in]	y2	Y coordinate of pt2.
[in]	c2	Color value of pt2.
[in]	tu2	Texture translation of pt2.
[in]	tv2	Texture translation of pt2.

Return values

void	No return.

void AEGfxVertexAdd	(	f32	x0,
		f32	y0,
		u32	c0,
