to keep source files under 1,000 lines of code.

inner implementation still only handles one dirty rectangle, but this way
we can prepare supporting applictions for the future.

rely on .la files for library dependencies.

are almost there.

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.

* Better CFLAGS and LDFLAGS propagation to the Makefiles.

<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.

major/minor computation scheme.

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.
