Miklos Vajna b6f0fd6a2f Related: tdf#149971 avmedia: add doc model and render for crop of media objects
It is possible to provide an explicit preview of media objects since
commit 8fa1d453c9 (Related: tdf#149971
svx: support explicitly provided snapshots for media shapes,
2022-08-24), however they can't be cropped.

This means that media shapes from PPTX with cropping show unexpected
content and can also have a buggy aspect ratio.

Extend avmedia::MediaItem to store cropping and take it into account
when returning the preview bitmap in SdrMediaObj::getSnapshot(). PPTX
import works out of the box, as oox/ already tried to set a cropping
property on the media shape.

This is just the preview, the cropping of the video itself is not yet
implemented.
