Subject: vidi/Timeline.py: add support for adding clips on their own layers
X-Git-Url: https://git.ao2.it/vidi-player.git/commitdiff_plain/7b9f8f4c6ed554ec3ec6e83e614ca9e9600ab913?ds=sidebyside

vidi/Timeline.py: add support for adding clips on their own layers

This can be used for instance to add a "background" clip, in case of
a midi file with intervals of silence, the background clip could be the
videofont sample representing a rest.
