Regarding getConstraints and the constraints given to gUM and 
applyConstraints(), I could use help from @jan-ivar .  The issue is 
figuring out how to be precise about what "semantic equivalence" would
 mean for different JavaScript objects passed in as arguments and 
returned from getConstraints().  In trying to write a PR for this I 
have been unable to find any approach that does not involve trying to 
enumerate equivalences not only of bare and ideal but also the various
 ways that objects can be equivalent.  Specifying the bare/ideal and 
any other constraint-mechanism-specific equivalences is fine, but I 
don't want to have to try to precisely enumerate equivalences among 
JavaScript objects that map to to the same WebIDL structure.  Any 
thoughts, Jan-Ivar?
