I got the idea (probably wrong, given my incompetence) that to make
rotations or other changes on the mask, the compositing engine of
Cinelerra is not suitable. A completely new compositing engine would
be needed to create matte on separate and independent alpha channels.
That's why in an old email I asked if it was possible to integrate
OpenFX, which would allow you to use a real rotoscoping tool, with all
the features required by you and me in the ticket 02 of MantisBT. But
I don't think it's possible: at least it means building a new
compositing engine or completely changing what's already there.
