There may be cases that would require a different ordering of the 
priorities listed here. One example would be how to express a preference 
for the best quality picture, and all being equal with quality, I'd 
prefer landscape rather than portrait aspect ratio.

With the fixed priority ordering described here I have the option of 
either forcing a landscape aspect, which may result in low quality, or 
asking for quality at the expense of giving up any preference for aspect.

A potential solution may be to actually express the constraints as an 
ordered list - then I can express the preference for aspect ratio or 
quality in the order that I specify the parameters.
