split is rendered moot by the plugin system: when enabled, binaries do
not link directly with libX11 or libGL. I hope this is a step towards
more consisteny and clarity.

* Renamed caca_refresh() into caca_display() which makes more sense.
  * Optimised gl_bgpal by directly storing floats instead of doing the
    conversion at runtime.
  * Handle resizing in cucul_set_size() and try to keep as much information
    as possible from the previous canvas.
  * Moved most global variables into cucul_t or caca_t contexts.
  * Moved time.c into libcaca.

+ Set the executable bit of caca-config when regenerating that file.
  * caca-config.in:
    + No longer use USE_SLANG_TRUE and USE_NCURSES_TRUE since we now
      have @CACA_LIBS@.

+ Changed section to libs/libdevel instead of games/games.
    + Changed package name to libcaca-dev.
  * debian/rules:
    + Use debian/compat instead of DH_COMPAT.
    + Install README, BUGS and TODO into /usr/share/doc.
  * caca-config.in:
    + First version of the config script.
  * configure.ac src/Makefile.am:
    + Build a static PIC library as well.
  * README TODO:
    + Various updates.
