In particular, fix misbehavior in case main and overlay input formats
mismatch (e.g. YUV420 and YUV444).

Force termination when the overlay stream ends. Simplify scripting logic,
for example when an infinite source is used to generate a background for
a composite video.

In particular, dedicate first paragraph to deliver a short description of
the filter.

Fixes read after free.

Avoid to write more than one cuepoint per track and PTS in
mkv_write_cues(). This avoids a later assertion failure on "(bytes >=
needed_bytes)" in put_ebml_num() called from end_ebml_master(), in case
there are several cuepoints per track with the same PTS.

This may happen with files containing packets with duplicated PTS in the
same track.

change the treatment of the strip y coordinates which previously did
not follow the description (nor did it behave like the binary decoder
on files with absolute strip offsets).

The new code is also faster and more robust.

As for the performance:

old decoder + conversion to rgb:         fps = 2618
old decoder, without converting to rgb:  fps = 4012

new decoder, producing rgb:              fps = 4502
