To elaborate on this just a bit; the video stream displays various
libmodplug text info using the bintext decoder.

The user can set a color formula in order to display some fancy old school
demo effect (feel free to propose anything btw). Available parameters are:
 - basic math: E, PHI, PI
 - char coords: x, y
 - window dimensions in char: w, h
 - t: the timestamp in 1/1000 tb
 - libmodplug current values: speed, tempo, order, pattern and row

By default the libmodplug values are displayed (and can be disabled using
-video_stream_ptxt 0). If you want to set a formula, use
-video_stream_expr. You will also need the -video_stream 1 switch.

Of course, you also need the bintext decoder enabled.

I might need to write a doc about this, but I'd like opinions on this
before.
