Fix scaling detection for portrait displays

[AndreasBackx]

Fixed calculating the needed resize for portrait displays. The Size struct passed to image_util::rotate_image_buffer was at some moment changed to include the transformation already but wasn't changed there.

Tested using the following setup:

1. Left: 1.25 scale 4K portrait
2. Middle: 1.25 scale 4K landscape
3. Right: 1.25 scale and 4K portrait that was changed to 1.0 scale to see if it worked.

JPG used below as PNGs were too big to upload here.
