Thanks Hugh for the patch. Can you describe a little bit in detail what the patch does?

thanks!

Conceptually:

• assumes that first and last points are the ends of a line
• checks that the points in between are consistent with this hypothesis
• if so, then replaces the wiggly multi-point line with this line

Concretely:

• checks that no point is further from the line than 1/10 the length of the line
• checks that the distance of each point from the start point increases monotonically

(By the way, note that I have 1920x1280 laptop monitor. This is relatively high resolution, for a 14inch display, so it is possible that my mouse is more sensitive than if one was using a similar resolution on a larger display, or a lower resolution display. So, it is possible that the original algorithm works too, but needs to have some customizable sensitivity adjustment perhaps)
