[Feature request]: Bring VLC adjustments and effects into GridPlayer

[the-liquid-metal]

Suggestion

As analytical objects, sometimes some movies do not align correctly with the others. Its must be edited before analized. Since GridPlayer uses libvlc, and VLC is able to display movies that have been simply manipulated without changing them permanently, GridPlayer should be able to do it too. Even though they are basic, VLC adjustments and effects are quite comprehensive, though some effect are not relevant for analytical task.

It would be great if all the relevant ones are included. Although it is subjective to analytical aspects which people work with, i think the most basic adjustments is geometric transformation, which you can find it on: Tools > Effects and Filters > Video Effects > Geometry > transform. The other is brightness adjustment, which you can find it on: Tools > Effects and Filters > Video Effects > Essential > Image adjustment.

Adjustments and effects are suitably applied to a "single movie". Although functionality for "all movies", can be provided as well. This means we can first applied to "all movies", and than tweak to a particular movies.
