Use "standard" shadowing in the Font.spaceWidth method

Browse Source 
With `Font.exportData` now only exporting white-listed properties, there should no longer be any reason to not use standard shadowing in the `Font.spaceWidth` method.
Furthermore, considering the amount of other changes to the code-base over the years it's not even clear to me that the special-case was necessary any more (regardless of the preceding patches).
