* Changed the line, box, ellipsis etc. prototypes so that they use an UTF-8
    string instead of a single character as their last argument.

canvas size (use cucul_init(0, 0) for the old behaviour).

* 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.

of unicode letters) is now separated from the higher level rendering and I/O
(that is, libcaca). This commit totally breaks the API, but once everything
is polished I will think about source-level backward compatibility. Most
drivers are broken, but X11 still sorta works.

  The new design is much more object-oriented and allows having several
active renderers at the same time, changing renderers on the fly, and more
important, having no renderer at all (useful for converters, or when you
want to do your own renderer).

  And in case you are still wondering, the libcucul acronym has "Unicode"
because I want to support at least a subset of Unicode. There are awesome
glyphs in it, including the ones inherited from Codepage 437 such as
"gray 25%" that are used in DOS and Win32 ANSI art.

+ Moved spritedit to the test/ directory, because it is not mature enough.
  * libcaca.spec debian/control debian/rules:
    + Do not install caca-spritedit.

      in order to select events.

+ Added caca_wait_event(), a blocking caca_get_event().
  * src/ examples/:
    + More documentation.
  * doc/doxygen.cfg.in:
    + doc/doxygen.cfg is now generated by configure, so that we can use
      @top_srcdir@ and we no longer need to hardcode PROJECT_NUMBER.
    + Create manpages.

+ Added setab/setaf quotes from the XTerm terminfo.
    + Proposed a workaround for bright colours on any terminal.
  * src/caca.c:
    + 16 colour support for ncurses and conio.
  * src/graphics.c:
    + Ported to 16 colour support.
    + Added a missing <stdio.h> for BUFSIZ.
    + Disabled vsnprintf under DOS (only vsprintf exists).
  * examples/:
    + Don't abort if the caca.txt sprite was not found.
    + Ported to 16 colour support.

+ Renamed sdl_get_key() into sdl_get_event().
    + Handle mouse clicks.
  * src/caca.c:
    + Activate the terminal's mouse handling if supported.

+ Added caca_set_dithering() (unused yet).
    + Added random dithering.
  * src/caca.h:
    + Renamed legacy EE_* enums to CACA_*.
  * examples/demo.c examples/caca.txt:
    + Added a default sprite for libcaca.

to examples/.

+ Renamed ee_color() to ee_set_color(), wrote ee_get_color().
  * libee/line.c:
    + Implemented draw_polyline() and draw_thin_polyline().
  * libee/sprite.c:
    + Removed the f member of struct ee_sprite.
    + Implemented ee_get_sprite_{width|height|dx|dy}().
    + Restore the color fater ee_draw_sprite() is called.
  * libee/box.c:
    + Fixed a bug causing improper box clipping at the right and the bottom.
  * data/foo_fighter:
    + Fixed bugs in the sprite.
  * src/intro.c:
    + Test effects for the future game's intro.
  * test/spritedit.c:
    + Added stuff to the sprite editor. We can now navigate through frames.

+ Placeholder for our upcoming sprite editor.
  * src/Makefile.am data/Makefile.am:
    + Use AM_CPPFLAGS, not target_CPPFLAGS, so that automake-1.5 can be used.

+ Moved ee_get_key() here.
  * libee/math.c:
    + Moved r00t() here and renamed it to ee_sqrt().
    + Moved GET_RAND() here and renamed it to ee_rand().
