Bug 763734 - better decimal places for physical units.

Browse source 
Compute the ideal decimal precision for cursor position and length
status so that you get the best precision on physical units depending
on the current resolution, yet avoiding over-precision (which can be
misleading). The unit's "digits" value is now used as a minimum
precision only.
