caca_wherey(), in order to match the old <conio.h> naming scheme.

speedups when the calling application knows the dirty rectangle covered by

display driver to clean up its shit. Fixed X11 driver accordingly.

different from what was already there.

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.

lesson to you: unit tests are good.

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.

are almost there.

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.

* Use size_t and ssize_t where appropriate.

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

<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.

* 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().

  * 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.
