Cannot scale album art

[Vankog]

EXPECTED BEHAVIOUR

Adjusting the album art to adjust to a changed toast size.

ACTUAL BEHAVIOUR

While the font sizes can be scaled, the album art cannot, which leads to strange visuals when changing the toast size.

STEPS TO REPRODUCE THE BEHAVIOUR

1. increase toast height and width
2. you can adust the font sizes accordingly
3. you cannot adjust the art size
