#2284 fix aspect ratio with "resize to window"

For some reason the height is getting scaled twice for ugoira, causing a
messed up aspect ratio because it was relative to the current height.
This makes it relative to the original height, so it should always be
correct even after multiple scales.
#2284 resize ugoira controls with image
#2284 hide resize notice
