Changes 2.12:
- Bug fix release for 2.10
- The gd plugin for font handlers was not being used at all if the build
  did not use fontconfig, e.g., on Windows. In addition, the code had
  dropped the name mapping to Windows font names.
- PostScript output had an extraneous '%' character on the first line,
  which would cause printing to fail.
- Text handling, during both sizing and layout, incorrectly handled
  empty lines such as label="\nabc".
- HTML-like tables had been changed to use too much vertical space,
  to possibly use the wrong font in calculating the height of a line,
  and to use the wrong offset when moving the baseline from one line to
  the next.
