Set color method for sketches now affects text as well.
Set color method now changes the fill of wedges. Introduced problem with color transition overriding other transitions. Make sure to call setColor after previous sketch transition is finished.
Removed special lit class from hexagons

class was unecessary after changes, and was causing gray highlighting which
was different and wrong.
Tried working on hash-wedges. Code is commented out for now.
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
