theora: export cropping information instead of handling it internally
h264dec: export cropping information instead of handling it internally
h264dec: be more explicit in handling container cropping
hevcdec: export cropping information instead of handling it internally
This commit is a noop.
This changes the cropping behavior, when it's supposedly only meant to move
it outside of the decoder.
See https://ffmpeg.org/pipermail/ffmpeg-devel/2017-May/211239.html for the
discussion about it.
