speedups when the calling application knows the dirty rectangle covered by
a complex operation.

a more natural (x,y,w,h) 4-tuple to handle.

inner implementation still only handles one dirty rectangle, but this way
we can prepare supporting applictions for the future.

we currently mark far too many cells as dirty. This must be optimised.

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.

far better for error checking.

<cucul.h> will provide the C99 types, even if libcaca has been installed.
  * Rename what's left of "common.h" to "stubs.h".
  * Remove all references to erroneous <inttypes.h> from source files.

* Renamed cucul_*_canvas_frame() to cucul_*_frame() because we bloody well
    know that a frame belongs to a canvas.

* More debugging information in the import/export and font functions.

* Updated TODO.

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

  * Created cucul_set_attr_ansi() and cucul_set_attr_argb() which are bound

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

  * Made cucul_buffer_t an opaque structure and implemented the two getters
    cucul_get_buffer_data() and cucul_get_buffer_size().

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.

+ Updated the package descriptions to include cacaball.
  * doc/cacademo.1 doc/Makefile.am:
    + Use the cacademo manpage as the cacaball manpage.
  * src/:
    + Added #ifdef _DOXYGEN_SKIP_ME here and there to prvent Doxygen from
      documenting bizarre stuff.

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

+ 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.

+ Doxygenated public functions.
