bool pixel_view	(	unsigned &	i0,

bool vgui_section_render	(	void const *	pixels,
		unsigned	w,
		unsigned	h,
		float	x0,
		float	y0,
		float	x1,
		float	y1,
		GLenum	format,

	)

Render the pixels onto the frame buffer.

This renders the portion of the image within (x0,y0)-(x1,y1). The whole image is rendered if (x0,y0)==(0,0) and (x1,y1)==(w,h). (Actually, for efficiency, only the portion overlapping the viewport is ever rendered.) format and type encode the data encoding in pixels. pixels is assumed to store a row-ordered set of byte-aligned values.
