Removed special lit class from hexagons

class was unecessary after changes, and was causing gray highlighting which
was different and wrong.
Paths in sketch tool

A literal SVG path can be specified as data for the sketch tool.  I could have done this using
xy data in an identical fashion to line graphs, but this doesn't help me get the freeform shapes I need to highlight areas on an image for hotspots.  I can get the svg directly out of illustrator, so I used that instead. Note that it doesn't get scaled, so is somewhat imperfect.
removed oldstyle tests
Fixed nasty bug where radius was miscalculated for circles

In the case where scale doesn't start at 0, this gave back the wrong value for radius of a circle.
Did the math right.
