New filter:
- joincolors - tex4ht produces an element with unique id for each
\textcolor and other variants of color commands.
This filter replaces ids with common name for all elements with
the same color and removes the duplicated colors from the CSS file.
This results in substantial file size saving.
Bug fixes:
- fixed odtimagesize filter
- fixed $HOME directory lookup on Windows
make4ht is a simple build system for tex4ht. It is both
executable, which simplifies tex4ht execution, and a library
which can be used to create customized conversion programs.
