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.

* Use size_t and ssize_t where appropriate.

completely breaks compatibility with previous versions of libcaca on
    64-bit systems.

accordingly.
  * The C++ test example no longer needs "config.h".

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

* Partial update of the C++ bindings.
  * Updated documentation.

--This line, and those below, will be ignored--

M    cxx/cucul++.cpp
A    cxx/cxxtest.cpp
M    cxx/cucul++.h
M    cxx/Makefile.am

and background colours to clear the screen.

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

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.

cucul.c just in case.
