@rexrainbow , you don't have to apologize, you are doing us a favor here
I'm not sure what results I should get from this behavior, I saw your Laser effect example but I'm still uncertain.
I find that there is little difference when "Pixels per step" is 10 or 100 and no difference at all when the values are 100 or 1000000. Only on very small values I can notice a clear difference: 1 will produce a smooth line (excellent for trails by he way!) while 5 will give a dotted line. On higher values, only on very fast movements there are big gaps between the dots and the distance seems to be loosely linked with the speed of the movement. The actual value of the "Pixels per step" parameter however doesn't seem to be reflected on those gaps. Meaning that a 100000 value doesn't produce a 100000 pixel gap or something similar to that.
Furthermore, other than linear "Steeping mode" no other setting works and with in the conditions, the "On horizontal step" and "On vertical step" doesn't work either.
I've attached a screen capture that shows some of the above. Does these results look as expected?
