"""Hello-world for TTF font loading in Reportlab.

This does seem to work, embedding the fonts (or perhaps the relevant
parts of them) into the output file, and smoothly handling layout that
switches fonts and even typeface sizes, and producing a funny page size.
The output PDF file is only 53K, even though it includes text in both fonts,
which are 71K and 74K respectively in TTF format; they don't even gzip
that small.  userguide/ch2a_fonts.py does document the font support
as embedding subsets of fonts in the PDFs.  I don't think it's embedding
the Chinese font, but rather using the system font (if you have it).
