In this patch, we remove all the versions of each wallpaper that are not the largest size. Here are the reasons why:
- **It's no longer necessary:** The old method appears to have been an artifact of the days before wallpapers could differ from the aspect ratio of the screen without looking bad. This is no longer a technical constraint that we face.
- **Simplicity:** It's easier to manage wallpapers, add new ones, and edit existing ones if you only have to do it for one image, not 15 or more.
- **Size savings:** installed size on disk falls from 152 MB to 25 MB.
The increase in memory use for any existing user is negligible (< 1MB).
