Tim-Philipp Müller 6630236af4 video: add video overlay composition API for subtitles
Basic API to attach overlay rectangles to buffers,
or blend them directly onto raw video buffers.

To be used primarily for things like subtitles or
logo overlays, not meant to replace videomixer.

Allows us to associate subtitle overlays with
non-raw video surface buffers, so that subtitles
are not lost and can instead be rendered later
when those surfaces are displayed or converted,
whilst re-using all the existing overlay plugins
and not having to teach them about our special
video surfaces. Could also have been made part
of the surface buffer abstraction of course, but
a secondary goal was to consolidate the blending
code for raw video into libgstvideo, and this
kind of API allows us to do both in a way that's
minimally invasive to existing elements, and at
the same time is fairly intuitive.

More features and extensions like the ability to
pass the source data or text/markup directly will
be added later.
