[MPlayer-dev-eng] [PATCH] Decode economy

[Sergey Khlutchin]

Hi!
When the size of video is more than the size of its visible part,
it is possible to accelerate decoding not making transformations of invisible blocks of the picture.
The attached patch counts the picture visible part in view of used filters and location of the MPlayer's window inside of parents.
It was necessary to do changes in different parts, probably some places are insufficiently elegant,
and I would like to discuss it.
This code works for -vo x11 and MJPEG generated by Elphel camera.
