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.

become ugly). You can now emulate the previous network driver behaviour
    by doing: "CACA_DRIVER=raw cacaplas | cacaserver".

can add new exporters without changing the API.

that has all the functionality, except it does not work yet (the stdin
    reading routine is missing).

    and the exporter in libcaca but I'll find a way to harmonise that.
