/** Font metrics. The only way to generate accurate images
* in any format that contain text is to know the font metrics.
* Specifically, we need to know the width of every character and the
* maximum height (since we want all characters to fit within same line height).
* I used ttf2tfm to dump the font metrics from Mac TrueType fonts and
* then converted that to a Java class for use in a PostScript generator
* for trees. Commands:
*
* $ ttf2tfm /Library/Fonts/Arial\ Black.ttf > metrics
*
* Then run metrics into python code after stripping header/footer:
*
#
# Process lines from ttf2tfm that look like this:
# Glyph Code Glyph Name Width llx lly urx ury
# ------------------------------------------------------------------------
# 3 00020 space 333 0, 0 -- 0, 0
