Hi Daniel,
you make perfect sense as usual. :-)

Hi,
there is some hardware than can do 2D compositing with an arbitrary
number of planes. I'm not sure what the absolute maximum number of
planes is, but for the discussion, let's say it is 100.
There are many complicated, dynamic constraints on how many, what size,
etc. planes can be used at
