LeafDemuxer fixes (the experimental data-sequence driven
fragmented mp4 demux).

Some muxers are interleaving using single trun/fragments,
Moov()->Moov(A)->Moof(B)
instead of interlacing truns withing fragments.
Moov()->Moof(A,B)->Moof(A,B)
Example: BigBuckBunny ismv file

Another problem is that data isn't interleaved at all
at end of tracks, and there's a long trailing gap of
audio fragments only.
Moov()->Moov(A)->Moof(B)->Moof(B)->Moof(B)->Moof(B)

Only the type is useful here. The other parameters are the same for
all video outputs (i.e. copied from vd->cfg), and should already have
been taken care of when the window was created.

(no functional change)

Even though that pragma is standard C99, MSVC doesn't understand it.

This duplicates the 7-years older "zoom" option for no good reasons.

This makes sure that the "crop" variable always represents the current
crop settings.

The video output variables currently represent the wanted state, not
the actual state. Forcefully resetting them to the actual state with a
delay can create feedback loops. (Indeed some of the code paths had
already been commented out for that exact reason.)
