dimension.py
An Inkscape effect for adding CAD style dimensions to selected objects
in a drawing.

It uses the selection's bounding box, so if the bounding box has empty
space in the x- or y-direction (such as with some stars) the results
will look strange.  Strokes might also overlap the edge of the 
bounding box.

The dimension arrows aren't measured: use the "Visualize Path/Measure
Path" effect to add measurements.

This code contains snippets from existing effects in the Inkscape
extensions library, and marker data from markers.svg.
