* 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.

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().

documentation errors or imprecisions.

fullwidth characters.
  * Added a case to test/fullwidth.c for cucul_blit and fullwidth chars.

* Fullwidth support in all exporters.

what you are importing.

* Use that in the SLang driver so that it supports UTF-8 input.

int which shall be used as an UTF-32 character. We do not have any casting
    problems due to the signedness of chars because all characters were
    ASCII (ie. <= 0x7f) beforehands.

* Started changing function prototypes so that they return an integer
    instead of void, just in case they might fail.

in all .c files that needed it.

and background colours to clear the screen.

choose the background colour.

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

* Added cucul_set_truecolor() for non-ANSI colours.
  * Added new argb32 -> rgb12 conversion functions.

remove redundencies in the Doxygen documentation.

really portable, and Visual Studio complains when they are not explicitely
    cast.

* Changed the line, box, ellipsis etc. prototypes so that they use an UTF-8
    string instead of a single character as their last argument.

onto the other with an optional mask.

that is a bit more high level than characters.
