#52 fonts are not set correctly when rendering to pdf

[Donovan Baarda]

This bug applies to version 1.18 and older.

drawstring in renderPDF.py uses addLiteral instead of
setting the font correctly and using the canvas'
drawString. This results in the wrong font being used,
and causes mis-alignment of text, most notable when
right-aligning bold text.

The bug is fixed by the patch available at;
