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

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

attached to it.

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.

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.

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().

cucul_attr_to_argb64() (previously _cucul_attr_to_rgb12bg,
    _cucul_attr_to_rgb12fg and _cucul_attr_to_argb4) in the official
    libcucul API.
  * Cleanup complete: libcaca no longer depends on "cucul_internals.h".

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.

functions to access its real data. This is a big API change that will
    break your software, sorry :(

collisions due to symbol mangling.

* Use caca_set_cursor() in test/input.c.

bit myself, too.

* Underline support in the X11 driver.

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().

resizes it later, or the driver changes it to fit the display.

with "utf8".

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.

such as cucul_dither_t instead of struct cucul_dither.
  * Made cucul_buffer_t an opaque structure and implemented the two getters
    cucul_get_buffer_data() and cucul_get_buffer_size().
  * Documented all missing functions and function parameters.

remove redundencies in the Doxygen documentation.
