  * Moved buffer-related functions to cucul/buffer.c.

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

list of available formats. Also added a few truecolor blocks to the test.

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.

* Fixed font selection through cucul_font_load().
  * Added a bigger 10x19 bold font.

* Removed ugly hooks from test/font.c.

* Documented most font functions.
  * Cleaned up cucul_render_canvas() and made it actually usable by external
    programs. Removed ugly printf() debug calls.

really portable, and Visual Studio complains when they are not explicitely
    cast.

environment variables handling. Replaced that with three per-bitmap
    functions: cucul_set_bitmap_antialias(), cucul_set_bitmap_color() and
    cucul_set_bitmap_dithering().
  * Added cucul_set_bitmap_brightness() and cucul_set_bitmap_contrast()
    prototypes (but did not implement them yet).
  * Added cucul_set_bitmap_charset() to choose what characters are going
    to be used for the bitmap rendering.
  * Removed the now useless cucul_get_feature(), cucul_set_feature() etc.

  * Fixed coding style.
