The problem with T98683 is that sampling interval can be set to very small, resulting in very dense points. This patch attempts to optimize that a little bit.

I don't think I can pin point an exact value that's appropriate, but I found the UI limit of 0.01 is still somewhat needed to create some dotting effect in default geometry scale with a reasonably thin line art set up. I changed the UI limit to 0.05 (which looks nicer in default thickness on a default monkey) and set an absolute minimum of 0.005. Very small value would cause the algorithm to run very slow anyway so probably not a very good idea.
