Comment (by Otto42):

 After banging my head on a wall for 3 weeks on this one, I'm inclined to
 say push it to 3.6 or "wontfix" it.

 Basic problem as I stated before: backgrounds don't have any indication as
 to widths.

 Two cases to consider:

 - BIG background images have an inherent problem in that we don't know
 what the intended width of the background image is supposed to be. So if
 the image is large, do we half-size it and use the uploaded version as the
 HiDPI version?

 - SMALL background images have an inherent problem in that scaling small
 images down looks terrible. If you take a 32px tiled image as the HiDPI
 version, and scale it down to 16px for the normal case, it looks just
 awful. Every site that has HiDPI tiled backgrounds includes two separately
 made versions of them at each size (ask koop to show you some example
 sites with HiDPI tiled images). So you kinda need a second uploader.

 I have no solution to this problem. Everything I've tried short of adding
 an entirely separate image uploader box has a major downside.

 Suggestions welcome.
