DJV 3 - Feature request - Anamorphic desqueeze

[aberkl]

A certain number of camera original files are shot anamorphic. DJV should at least support the most common 2x anamorphic images (squeeze factor = 2).

Not sure where this option should be placed, but I guess TOOLS > VIEW is probably not a bad idea.

See also #689 and https://en.wikipedia.org/wiki/Anamorphic_format

There are other squeeze factors, more or less used. So, if the default desqueeze would be a text-box with "2.00", you could type in other, less common factors.

Indeed, anamorphic / non-square pixel aspect ratios are rather common with camera footage.
