And I’ll tell you.  Unlike the previous incarnation where the primitives were generated one pixel at a time (very inefficient), this time it’s using polygons to generate the primitives. So a line is using the line drawing on the video card, the rectangle and unfilled ellipse are using the line drawing as well and the filled ellipse is using triangles.  So all in all, they’re MUCH faster than the previous version.   For more details click the thingy at the bottom there…
