Measure widget doesn't show distances less than 1.0 measurement units
The measure widget is currently coded in such a way that it does not show lengths for segments shorter than one full measurement unit. If the units are meters, this is usually not a problem, but if the units are set to miles or degrees only very large segments will be processed.
I believe the intended purpose of the code is to eliminate processing of segments that are very short in screen (pixel) units. I will attach a patch to this ticket for review that makes the necessary changes.
the patch looks good, please commit it.
