as plugins. This way, libcaca does not directly depend on those libraries.

just need to include <caca0.h> instead of <caca.h> and should be source-
    compatible with old versions of libcaca.

    Most of the old API works, except features and caca_sqrt(). Sprites do
    work API-wise but due to the new format they are no longer working in
    the same way.

from an alternate directory (they failed to find common.h).

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

broken, and event handling is not yet in the driver-specific files, but
    I will of course fix that later.
