This patch fixes a visual issue where the QuickLook previews/thumbnails of blend file (introduced in PR #107072) would have a distorted square aspect ratio instead of their original aspect ratio. Fixed by using the original image aspect ratio scaled to honor the QLFileThumbnailRequest's maximumSize as per the official documentation[1].
