Created attachment 354090 [details] [diff] [review]
We were failing a few of the style system mochitests because the spec says that 'normal' should lead to a computed value of '0'. This could be trivially fixed in the computed style code, but given that they should be treated the same way, I don't see any reason to propagate the difference between the two so far.
This changes things so we change mWordSpacing from nsStyleCoord to nscoord. (The spec still says 'letter-spacing' should have a difference between 'normal' and '0'.)
