Fix a MediaValues::computeLength bug and add unit tests

MediaValues::computeLength had bug where the multiplication factor was an int, instead of a double.
That resulted in skewed computed values for viewport units.
This CL fixes that, and adds unit tests to make sure computeLength calculate length values correctly.
