Bugfixes cleanups

In a way they are. In a future not so far from now, we should add a way to render different layers of glyphs--each can be turnded on and off separately: an outline layer, a skeleton layer, a layer displaying point positions (probably with a way to access more information about points and their cps values). In that future, we wouldn't use both methods at the same time.
Right now it's a handy way for me to display the outline and the center-line at the same time; for that, I also have to turn of filling of the path in the angular glyph-directive.
