I know what pixel aspect ratios are. All too well, actually—for
instance, the square-pixel equivalent of 720x480 widescreen can be
either 853x480, 854x480, 856x480, 864x480, 873x480, or 875x480
depending on whom you ask. What fun! I actually attempted to explain
this in another thread:
<http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2009-December/024541.html>

So, yes, I realize that those dimensions are PAR-compensated. Most
users don't, which is why the shorthand form doesn't do them any
favors.
