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

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

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_*.

as bold or underline. No higher level support for these yet, but at
    least everything is consistent.
  * Created cucul_set_attr_ansi() and cucul_set_attr_argb() which are bound
    to replace cucul_set_color() and cucul_set_truecolor().

0.x glue code.

just need to include <caca0.h> instead of <caca.h> and should be source-
    compatible with old versions of libcaca.

    Most of the old API works, except features and caca_sqrt(). Sprites do
    work API-wise but due to the new format they are no longer working in
    the same way.
