Comment (by cmbarton):

 Well, if d.measure had the architecture to accept coordinate pairs and
 return line lengths and areas defined by the coordinate pairs, this would
 have been easy to implement in the GUI.

 BUT, d.measure ran as a persistent process that only accepted input from
 interactive drawing in an xterm emulation environment.

 So, measurement has had to be recreated entirely in Python/wxPython. And
 as you say, area calculations are tricky.
