Description
vendor/lineage: add rescaled boot animation for volla tablet in portrait mode
The current aspect ratio of our boot animation does not play well with Volla tablet 2560x1600 screen.
We need to re-scale the boot animation such that it is displayed in the original dimensions instead of being squished vertically.
