<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.

without using environment variables..
  * Implement caca_get_display_driver() to return the current display's
    output driver.
  * Add a simple example program to test caca_create_display_with_driver().

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

create a canvas when so.
  * Add caca_get_canvas() to retrieve the cucul canvas.

direct cv->chars and cv->attrs access by display drivers.

drivers no longer need to access the cv->refcount private member
    and __cucul_set_canvas_size() is no longer needed.

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

as plugins. This way, libcaca does not directly depend on those libraries.

* Fix cucul_utf32_to_cp437() call in the VGA output.

and return a value.

* Set ncurses's priority higher than slang.

* Code enhancements in the ncurses driver.
  * Added a comment to explain why slang has a higher priority than ncurses.

in all .c files that needed it.

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

remove redundencies in the Doxygen documentation.

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

and simplified the handle_resize() API. Still can be polished.

files. Phew. Now they just need a few comments.

properly credited authors and documented a few things.

broken, and event handling is not yet in the driver-specific files, but
    I will of course fix that later.

now because we only do ASCII, but that will let us do Unicode later.

* 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.
