Explicitly specifying the * in *x allows more flexibility in the future 
for cases such as:
- If sometime most displays will have 2x or higher resolutions, authors 
might want to set 1x versions aside.
- If 3x or whatever displays should occur, the spec should be suitable 
for them, too.
- Some UAs might decide to progressively load sources in order to 
emulate what we know from interlaced GIFs. Authors could for this 
purpose add 0.5x and even 0.25x versions.
