as multiboot kernels.

properly credited authors and documented a few things.

* 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.

+ Removed caca_internal.h from the list of documented files.
  * src/:
    + Minor documentation updates.

+ Added caca_wait_event(), a blocking caca_get_event().
  * src/ examples/:
    + More documentation.
  * doc/doxygen.cfg.in:
    + doc/doxygen.cfg is now generated by configure, so that we can use
      @top_srcdir@ and we no longer need to hardcode PROJECT_NUMBER.
    + Create manpages.

+ Doxygenated public functions.

+ Doxygenated a few things.

to examples/.

+ ee_sqrt() now uses unsigned ints.
    + Avoid overflows in ee_sqrt().

+ Added ee_color_names[] containing our 16 color names.
  * libee/ee.c:
    + Extended our color set to the full 16 instead of 10.
    + Precalculate ncurses attributes.
  * libee/graphics.c:
    + Clip color value in ee_set_color().
    + Clip characters in ee_putchar().
    + Partially clip characters in ee_putstr(), overflows aren't checked yet.
  * libee/ee_internals.h:
    + New file to share extern variables within libee.

  * test/demo.c:
    + Added a simple demo_color() to output all colors.
    + Replaced four ee_draw_line() with ee_draw_thin_box().
    + Replaced x1, y1, x2 etc. with xa, ya, xb etc. because <math.h> already
      defines y1.
    + Randomized colours from 0 to 15 instead of 1 to 10.

  * src/Makefiles.am:
    + Added -lm to the ttyvaders linking flags because of the intro.

  * README BUGS TODO:
    + Updated.

+ Moved ee_putstr() and ee_putchar() in here.
  * libee/ee.h:
    + Got rid of ee_goto().
    + Moved <slang.h> or <curses.h> into libee.
  * Replaced ee_goto()/ee_putstr() pairs with ee_putstr().
  * Ditto for ee_putchar().

+ Moved ee_get_key() here.
  * libee/math.c:
    + Moved r00t() here and renamed it to ee_sqrt().
    + Moved GET_RAND() here and renamed it to ee_rand().
  * src/math.c:
    + Removed this deprecated file.

* factorized the seeker generation on fragbomb explosion.

* new super weapon, the fragmentation bomb.

* added GPL headers to source files.
