* 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.

that has all the functionality, except it does not work yet (the stdin
    reading routine is missing).

that we have one function less.

* Print a small message at kernel boot time just to check that the kernel

files. Phew. Now they just need a few comments.

* Added a build-dos script to cross-compile the DOS version using djgpp.

properly credited authors and documented a few things.

broken, and event handling is not yet in the driver-specific files, but
    I will of course fix that later.

* 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.

+ Refresh the X11 window when an exposure event is received.
    + When resizing the X11 window, start showing extra characters when two
      thirds are visible.

+ The ncurses and S-Lang drivers properly return CACA_EVENT_RESIZE.
  * test/event.c:
    + Display CACA_EVENT_RESIZE.

+ Added the CACA_EVENT_RESIZE event.
    + Added caca_get_mouse_x() and caca_get_mouse_y().
  * src/graphics.c:
    + Window resize handling in the X11 driver.
  * examples/aafire.c:
    + Fixed a bad assumption in the resize handling code.

+ Native win32 port.

+ Check for gettimeofday().
  * src/time.c:
    + Created _caca_time().
    + Ported _caca_getticks() to the Win32 API.
  * src/caca.c:
    + Properly builds on Win32.
  * test/event.c:
    + Added <stdlib.h> because we use malloc().

+ Do not refresh after each event, but only when there is no event
      pending.
    + If the pressed key is a printable character, display it.
  * src/time.c:
    + Moved _caca_getticks() to this file.
  * src/caca.c:
    + Set the escape delay to a very low value in the ncurses driver,
      because I don't want escape sequences to be entered manually.
  * src/io.c:
    + Autorepeat emulation in the ncurses and slang drivers: do not
      immediately send the key release event.
  * configure.ac:
    + Check for usleep.
    + Improvements in the win32 platform detection.

+ Fixed a minor overflow in the saturation computation.
    + Use a global lookup table for foreground/background colour selection
      in the bitmap rendering routine. This broke dithering, sorry.

+ Mouse support in the X11 driver.

+ 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.

+ Support for simultaneously compiled-in drivers.
    + Honour the CACA_DRIVER environment variable.
  * configure.ac:
    + Drivers are no longer mutually exclusive.

+ Support for CACA_WIDTH, CACA_HEIGHT and CACA_FONT in the x11 driver.
    + Use an intermediary X pixmap for rendering.
    + Slightly changed the variable naming scheme.

+ Beginning of an X11 driver. Currently we merely open the window and
      check keyboard events.

+ Added antialiasing support.
    + Dithering, antialiasing and background mode can now be selected at
      runtime.
  * src/caca.c src/caca.h:
    + Renamed caca_dithering into caca_feature and extended the type to
      express background colour and antialiasing mode.
  * examples/demo.c:
    + Fixed a bug that disabled the sprite demo.
    + Draw solid flares.
  * examples/view.c:
    + Select antialiasing and background mode at runtime.

+ Moved global variables to src/graphics.c.
  * src/bitmap.c:
    + Sanitised prototypes.

+ Internally cache screen width and height.
  * src/bitmap.c:
    + Added alpha support to caca_draw_bitmap(). For now, we only treat 0%
      alpha as fully transparent, and any other value as fully opaque.
    + Slightly tuned colour weights in the renderer.
    + caca_set_bitmap_palette() takes unsigned ints.
  * examples/demo.c:
    + Added a crap render demo.
  * examples/aafire.c:
    + Set a 20ms delay.
    + Added alpha values to the palette.
  * examples/view.c:
    + Draw a gray checkered grid below the image so that transparent images
      look a lot nicer.
    + 'f' toggles "fullscreen" mode.

+ Moved graphics stuff from caca.c to graphics.c.
    + Added a few kludges: if gnome-terminal or konsole are detected, switch
      to TERM=xterm-16color to benefit from extended colour palette.

+ Doxygenated a few things.

+ 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.
