[Feature Request]: "Fit Width" option

Preflight Checklist

• I have searched the issue tracker for a feature request that matches the one I want to file, without success.

Describe your suggested feature

Mostly for spread pages in manga and such, this option would resize the spread page to fit the horizontal borders rather than going off-screen, avoiding the manual zooming out > zooming in > zooming out proccess which can be really common in some series.
Most manga sites have an option like that.

I know this is avaiable in the Vertical mode, but that comes with its own set of problems (it swings between spreads being fine but single pages being too close), I'm mostly referring to the Slide/Page Turn mode.

By default, images are already fit to the maximum available width/height (Respecting the defined margins). If an image does not fit to the desired size, it may be because Do not enlarge more than its original size is enabled, which prevents the image from being displayed larger than its original size. The image will also not fit to the full available width if it already occupies the full available height.
