## Math rendering up and running again

Now that we're back on Debian I got the math rendering working again. This time I did a hack to get it outputting black on transparent instead of black on white so they can be put over any background colour. Also a slight improvement in quality has been achieved by rendering the postscript stage much larger and then reducing the final result down at the end.

$e^x = \sum_{n = 0}^{\infty} {x^n \over n!} = 1 + x + {x^2 \over 2!} + {x^3 \over 3!} + {x^4 \over 4!} + \cdots$
