a more natural (x,y,w,h) 4-tuple to handle.

inner implementation still only handles one dirty rectangle, but this way
we can prepare supporting applictions for the future.

that anything outside the dirty rectangle is guaranteed to be unchanged, but
we currently mark far too many cells as dirty. This must be optimised.

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.

far better for error checking.

<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.

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.

collisions due to symbol mangling.

* Do not try to set the terminal title if TERM=linux.

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

documentation errors or imprecisions.

and return a value.

caca_set_display_time() and caca_get_display_time() for consistency.

in all .c files that needed it.

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.

remove redundencies in the Doxygen documentation.

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

they can force a resize. We need to find a way to make those specific
    cucul - caca interactions unavailable to the clueless user.

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.

enough for everyone. Maybe I'll reintroduce caca_set_size sometime in the
    future because it's libcaca who gets the resize events, after all.

dans la vraie vie, 0x007f7f7f et { 0x00, 0x7f, 0x7f, 0x7f } n'ont pas
    toujours les bytes dans le meme ordre, deuzio un unsigned int n'a pas
    toujours 4 bytes, et troizio tu pourrais au moins checker que ca fait
    pas de warnings et/ou que ca segfaulte pas !
