Comment 11 for bug 263166

I was suggesting a circle in that very short lines will have less information with which to decide the direction so if an instantaneous tap was to make a zero length line with end caps then what direction should that line point? A circle gets round this question. I would add two points to my previous suggestion:
1. The length of the line before it is replaced by a circle is set by a slider (such as the pen mass slider). A setting of zero would allow the random direction pair of end caps that I assume that you want to see (perhaps an indeterminate direction is set to horizontal?)
2. The radius of the circle comes from the largest pressure observed before the pen is released.
