lyx_mirror/src/frontends/Painter.C
Lars Gullik Bjønnes c46b7d8955 Merge the unicode branch into trunk.
- src/support/unicode.[Ch]: new files with functions for converting
  to and fro ucs4, ucs2 and utf8.
- src/support/docstring.h: specialization of basic_string that
  holds a uint32_t internally.
- Several functions changed to use char_type instead of char or unsigned char.
- Qt3 and Qt4 sends ucs2 on to core
- Gtk sends ucs4 on to core
- Read and write utf-8 .lyx files.
- font_metrics and painter updated to handle ucs4 chars as input.
- Quite a bit of ugly compability code, conversion string->docstring, etc.
- Have fun...
