Right now, the qtconsole uses matplotlib.mathtex to print LaTeX with the SymPy profile. This isn't very good looking, is slow, requires matplotlib, and doesn't support full LaTeX.

Better would be to support MathJax in the qtconsole, or to use LaTeX itself, using something like http://research.scios.ch/inet/doku.php?id=ipy_tex.

Also, it does not support printing lists of SymPy expressions with LaTeX a la #1399 correctly.
