> Fuzzy Matching

I just proposed keywords (and floats) for this. Specified inexact  
matches are the more universal approach, though.

What is the reason for choosing 12? Pretty much every aspect ratio  
ever used in practice lies between 0.08(3) and 12, unless I'm missing  
something.

Portrait already is the inverse of landscape.

I heard rumours, which might well be wrong, that EICTA chose a 7%  
margin for the requirements of their HD Ready logo to allow 17:9 and  
15:9 display of 16:9 data. In my opinion, that is too fuzzy a match;  
perhaps even 5% is too much.
