Dynamic layout change when zooming out

[KirbyComment]

You can zoom in pages with Ctrl + and the page dynamically changes it's layout so that the entire width of the page is visible and on screen. Zooming out with Ctrl - however keeps the layout the same and you're left with empty pillarbox areas. Changing this would allow replays with more lengthy comments to use less rows to display (if zooming out can prioritize on widening this field) like this example:

I don't really want to change this— the pillarboxing is very much intentional, because it's hard to read pages that are too wide. Part of the issue here is that we're truncating comments on the server-side by number of characters, which means Japanese comments wind up longer than ones in the Latin alphabet (because they're wider); we should probably be at least shortening comments so they don't take more than 3-4 lines under normal circumstances
