Parameters:

	gc	= Graphic Context
	point	= Pointf
	color	= Colorf

static void CL_Draw::point	(	CL_GraphicContext &	gc,
		float	x1,
		float	y1,
		const CL_Colorf &	color

Draw a point.

static void CL_Draw::texture	(	CL_GraphicContext &	gc,
		const CL_Texture &	texture,
		const CL_Quadf &	quad,
		const CL_Colorf &	color = CL_Colorf::white,
		const CL_Rectf &	texture_unit1_coords = CL_Rectf(0.0, 0.0, 1.0, 1.0)
	)			[static]

Draw a textured rectangle.

This is a convenience function. If using repeatedly, it is a lot faster to use CL_PrimitivesArray with gc.draw_primitives instead

static void CL_Draw::texture	(	CL_GraphicContext &	gc,
		const CL_Rectf &	rect,
		const CL_Colorf &	color = CL_Colorf::white,
		const CL_Rectf &	texture_unit1_coords = CL_Rectf(0.0, 0.0, 1.0, 1.0)
	)			[static]

Draw a textured rectangle with the selected texture at unit 0.

Usage: gc.set_texture(0, texture); CL_Draw::texture(gc, rect, ...); gc.reset_texture(0);
It is recommended to use CL_Image draw function instead of this function. CL_Image is faster because it internally batch draws

static void CL_Draw::triangle	(	CL_GraphicContext &	gc,
		const CL_Trianglef &	dest_triangle,
		const CL_Colorf &	color
	)			[static]

Draw a triangle.

static void CL_Draw::triangle	(	CL_GraphicContext &	gc,
		const CL_Pointf &	a,
		const CL_Pointf &	b,
		const CL_Pointf &	c,
		const CL_Colorf &	color
	)			[static]

Draw a triangle.
