- make sure at least one listener is set
- reformat code

current canvas. This is useful to export dirty rectangles. Accordingly,
add caca_import_area_from_memory() and caca_import_area_from_file().

code for clarity.

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.

* Synchronise parameter types in the C++ bindings with the C API.

prototypes. As they are equivalent, this does not break the ABI.

<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.

to cucul_import_memory() and try again later if it says "not enough data".

* Updated the caca importer to reflect that; only one frame is read at the
    moment.
  * Added an "utf8cr" export format for UTF-8 + CRLF exports.
  * Updated cacaserver to reflect file format changes.

a file and a memory area into a libcucul buffer.
  * Changed the cucul_import_canvas() prototype so that it uses libcucul
    buffers instead of simple memory areas.

in all .c files that needed it.

cucul_import_canvas().
  * Renamed cucul_create_export() into cucul_export_canvas() for consistency.

* Removed most code from the raw driver and replaced it with a call to the
    caca exporter.
  * Slightly changed the caca export format and updated code accordingly.
  * Improved cacaserver error reporting.

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

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.

become ugly). You can now emulate the previous network driver behaviour
    by doing: "CACA_DRIVER=raw cacaplas | cacaserver".

can add new exporters without changing the API.

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

that we have one function less.
  * Fixed coding style.
  * Removed FUCKING TABS.               ____.------.___
