Describe the bug

After loading a PDF slide deck with 16:9 page ratio, the slide is not suitably zoomed to fit fully on the presentation screen if the latter one has not the same ratio. E.g, the left and right sides get cut off when the presentation screen has 16:10 ratio.

To Reproduce

Import a PDF slide deck with 16:9 page ratio. Primary screen has 3440x1440 resolution. The presentation screen has 1920x1200 resolution.

Expected behavior

OpenBoard should always guarantee that the whole slide is displayed on the presentation screen after loading a slide deck.

Actual behavior

OpenBoard seems to zoom slides to fit the whole height of the screen causing the left and right side to get cut off.

Screenshots
