tdf#149971 avmedia: implement video crop support in the gsteamer backend
If a media shape had cropping defined, we already took that into account
when presenting a preview for it, but not during video playback.
The reason for this is that the preview may be set by a file importer
(e.g. PPTX) explicitly, in which case the preview is a bitmap we get
without any video processing.
As a start, implement video crop for the gstreamer backend (used on
Linux), and also pass in the media item (containing crop and other
properties) both during the edit view (MediaWindowImpl) and presenting
(ViewMediaShape). We pass in the whole media item, so in case later
other filters (e.g. black-and-white) are wanted, we have all that info
in the backends already.
Other backends (avmediaMacAVF and avmediawin) are untouched so far.
svx/qa/unit/data/video-snapshot.pptx is modified to have a yellow border
when cropping is unimplemented, which is now not visible with the
gtreamer backend, matching PowerPoint behavior. PPTX export was working
out of the box already.
