Implements a simple function to render halos using the fast algorithm even if the halo is smaller than one pixel.

I like the look of this and it seems promising. But I think we need more before/after cases to look at with .1 -> .5 range halos using the fast vs full approach. There may be cases where the faster method cannot draw thin enough halos. However, your improvements look great in the one reference image.

The halos look quite well for thin sizes, too.
