there are only a few aspect ratio standards for PC monitors:
* 4:3
* 16:9
* 16:10
* 256:135
covering them with only one wallpaper per ratio standard seems
logical, most users will change the default right away and
distributions tend to ship their own variations anyway so shipping
~30MB (originally KDE shipped ~80MB, not considering the extra) is
a waste, especially when most compression methods do not handle
images efficiently thus increasing the Live CD/DVD's size. nowdays
peopel tend not to care about disk-space since it is cheep but we
are targeting not only the future but old systems too that may have
20/40/60/80GB of storage available (just to name a few).
right now, with this change, only 4:3 and 16:10 are covered but
that will change.
