'10%' is the correct computed value - percentages are resolved at "used value" time.  However, the getComputedStyle function is a bit of a misnomer, and actually returns a mix of computed and used values.

Which properties return what is underdefined right now.  Ideally we should wait for the CSSOM spec to define this, but in the absence of that, we can look at what other browsers do.

In particular, Firefox returns used values for these properties.  I think that's useful, and we should probably match them.
