properly export cucul_utf8_to_utf32(). Evil API breakage, but no one
    uses these functions anyway.

cucul_set_color() and cucul_set_truecolor() under the new names
    cucul_set_color_ansi() and cucul_set_color_argb().
  * Renamed cucul_get_color_name() into cucul_ansi_to_str().

functionality into cucul_set_attr().
  * Add cucul_ansi_to_attr() and cucul_argb_to_attr().
  * Rename CUCUL_COLOR_* to CUCUL_*.

    a warning) and run, though.

now x/y/width/height instead of x1/y1/x2/y2. Avoids unnecessary +1/-1
    computations.

choose the background colour.

their name, eg. cucul_create() -> cucul_create_canvas() etc.
  * Moved buffer-related functions to cucul/buffer.c.

* Renamed canvas handle variables from "c" to "cv". Eh ouais mon gros.

such as cucul_dither_t instead of struct cucul_dither.
  * Made cucul_buffer_t an opaque structure and implemented the two getters
    cucul_get_buffer_data() and cucul_get_buffer_size().
  * Documented all missing functions and function parameters.

remove redundencies in the Doxygen documentation.

factored common-image.c file. Feature selection such as antialiasing or
    dithering mode are still disabled.

parameter to do what both functions did before, and even more.

* 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).

properly credited authors and documented a few things.

* 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 statusbar and help menu handling in separate functions.

+ Proper aspect ratio support.
    + Finer zoom support.
    + Handle mouse clicks as next/prev picture command.
    + Removed useless iterations in draw_checkers().

+ When resizing under X11, copy the old pixmap to the new one.
  * examples/cacaview.c:
    + Resizing support.

+ Renamed caca_set_title() to caca_set_window_title().
    + Implemented caca_get_window_width() and caca_get_window_height().
  * examples/cacaview.c:
    + Set the window title to cacaview.

+ Check for sys/times.h and unistd.h.
    + Added calls to AC_C_CONST and AC_C_INLINE.
  * src/time.c src/graphics.c:
    + Fixes for MSVC compilation warnings.
    + Additional sanity checks in the Win32 driver.
  * src/caca.c:
    + Use raw()/noraw() in the curses driver instead of cbreak().
  * msvc/libcaca.sln:
    + Added an MSVC solution.
  * examples/aafire.c:
    + Slightly reduced the maximum cacafire framerate.

+ Implemented caca_set_title() for X11 and Win32.
  * examples/cacaview.c:
    + Use caca_set_title() to set the window title to "cacaview".

+ Look for Sleep in -lkernel32.
  * examples/cacaview.c:
    + Use caca_wait_event() instead of usleep()/caca_get_event().

+ Native win32 port.

+ caca_get_event() and caca_wait_event() now accept a mask as an argument
      in order to select events.

+ Fixed a bug that caused ButtonRelease events to be forgotten under X11.
  * examples/cacaview.c:
    + Use <stdlib.h> instead of <malloc.h>.

+ Changed <const type> constructs into <type const>.

+ If Imlib2 was not activated, warn the user that only BMP is supported.

+ Use sprintf() instead of snprintf() so that cacaview builds with DJGPP.
  * examples/aafire.c:
    + bzero the pixel buffer in the initialisation routine.
