Correct for 1280x1024 aspect ratio

Something that's been bugging me, I'd like to see if anyone else agrees.

It's pretty well-known that a 1280x1024 isn't 4:3, it's actually 5:4. That means wallpapers and other things go out of whack, when viewing fullscreen. I was thinking that a 4:3->5:4 expansion could be done on 5:4 resolutions, and perhaps the reverse in other cases, although I expect it's less of a problem. This would only be done if you were using one of the fit to window modes, and only on 4:3/5:4 images, naturally - perhaps only in fullscreen (since the viewer has so many obstructions it doesn't really matter anyway).

Now that I think about it, this could apply to 16x9 (TV) and 16x10 (PC) resolutions also.

The math itself is easy and probably not hard to insert, but it's a pretty big change nonetheless.

Comments?

I am not sure to understand the solution you propose:
- Do you want the image to "fill the screen" but keep proportion? (a "fit over" option would make that)
- Or do you want the image to stretch to screen size? (a "Stretch" option would do that).

Both would fit into my previous suggestion to change the 'auto size' thing.
(I skipped/postponed it for 1.90 due to lack of support and other competitive discussions)

It'd be a stretch. But a plain stretch mode would distort everything to monitor dimentions (unless there's some kind of maximum aspect error), whereas this would only be done to correct bas aspect ratio for a specific range of files.

See, the problem is that the resolution is 5:4, but the monitor itself is 4:3. Unless you're into drafting this normally isn't a problem, but anytime you view wallpaper made for normal resolutions the letterboxing is glaringly obvious. All this would do is stretch 640x480, 1024x768, 1600x1200, etc wallpapers, and ignore others.

Same problem with widescreens: 16:10 resolutions in a 16:9 screen. But since 16:10 resolutions are the standard on monitors, there's not really any 16:9 wallpaper ratios that I know of. Just movies.

Maybe it's just too specific a feature, but I thought I'd throw it out there.
