playing around with mpl1 api
added mpl1 sketch
Clean up logging. Remove dead function.
Make \under and \over behave as in TeX. (i.e. it's {x \over y} not \over{x}{y})
Oops. Dotless i was already in there as \imath
make texmanager respect changes to rcParams after initial import
Make Cairo and Gdk backends work with new mathtext refactoring.
Support dotless i and j
Fix spacing when going from non-math to math.
Got SVG and PS (afm-only) support working. Still kind of tempermental.
