[css-values] calc() serilization

Hey all,

In working on some tests for the CSS Shapes test suite, I discovered that Blink and WebKIt disagree about the serialization of some calc() expressions. For example:

Expression: calc(10/100)
WebKit: calc(0.1)
Blink: 0.1

Expression: calc(10/100 + 30/100)
WebKit: calc(0.4)
Blink: 0.4

I've noticed that the CSS Values and Units doesn't mention anything about serialization for calc(), so I'd guess that there are probably other divergences.

Thanks,
Bem
