Daniel VoshartandClaude Sonnet 5.5 9715c90413 Meta: map Lightroom's quarter-turn region Rotation to the upright frame
Lightroom Classic stores the box of a photo with Exif orientation 6 / 8 in
the sensor's own frame and records the orientation as mwg-rs:Rotation
(-pi/2 for 6, +pi/2 for 8, 0 for 1) while AppliedToDimensions names the
upright size. Ignoring Rotation put every portrait photo's face box in the
wrong place. Convert such regions into the upright frame, with a synthetic
regression test for -pi/2, +pi/2 and 0.
