Creating cases for fonts

When creating cases for font-family, font-weight, font-variant, etc... How are we handling cases where a particular font in necessary on the system to verify the test? I recommend we add a flag for these cases so we can provide some sort of note to notify the tester that the case requires a specific font or fonts to be installed in order for the case to function properly.

font-weight for instance can require multiple fonts in order to test the algorithms for selecting the proper fonts to match to the numerical weights.

I think we should add a flag called 'font' to signify that a special font or fonts may be necessary.
