You are correct on both points. The primary value of the tool at this
point is that it removes the tedium of defining polygons to connect vertices.
It's a start!

Your edge-detection suggestion is certainly the ideal, but would get a bit
difficult for patterns with curved outlines. The progression as I see it
is: automatic meshing of text-defined outlines -> GUI with ability to draw
outlines graphically -> GUI with edge detection/some sort of automatic
outline generation. At least the first two are easy. :)
