Presenter: Add a "Resize to Fit Content" action

When resizing, it can be hard to get the content to appear nicely
without a black border where the window's aspect ratio doesn't match the
content's aspect ratio.

With this new action, it is possible to automatically adjust the
window's size to match the content's aspect ratio. When it is resizing,
it will maintain the width of the window, but adjust the height to match
the aspect ratio of the content.
