[Bug 797169] compositor: Remove crossfade property and implement a more extensible interface like in glvideomixer

[GStreamer (GNOME Bugzilla)]

--- Comment #22 from Sebastian Dröge (slomo) <slomo at coaxion.net> ---
Maybe as a way forward:
1) Remove crossfade code from compositor, implement a SRC and ADD mode (we have
the code for that already). That allows doing crossfading like now if all
inputs are fully opaque. This can then be moved to -base with videoaggregator
and everything.

2) Copy the old compositor to a new crossfadecompositor (better name please).
That can then be used by pitivi for the time being until we implement a nicer
and better crossfade/transition element. Which IMHO should also have additional
constraints (like no positioning, only same input sizes, only two pads, ...).
