Detailed Description
Measure length, angle and area in various ways.
Adjustable units: correspond to screen (inches or pixels), viewport, viewport+other transform, or any of those plus a correction factor, so you can have actual units be inches, for instance, but measure distances using 1 lightyear == .5 inches.
Left-click and drag with no current produces a line. Shows on screen the measurment. With current line, hover over endpoint, click drag to produce an attached line, measures both lines and angles. With more than one line, dragging a line to the initial point will close the line, producing an area measurement.
Modes:
- Measure line segments by default
- Measure angles not distances, assumes at least 2 line segments.
- Measure area, assumes free form line dragged out, close path automatically

Member Function Documentation
Creates new data if not click down on one...
Shift-click makes a new color spot.
- Todo:
- *** shift-click near an already selected but perhaps obscured point should not select the point that is obscuring it instead
