ok = pfontdesc:Equal(desc2)
Two font descriptions are considered equal if the fonts they describe
are provably identical. This means that their masks do not have to match,
as long as other fields are all the same. (Two font descriptions may
result in identical fonts being loaded, but still compare False.)
This function returns True if the two font descriptions are identical,
False otherwise.
True if the two font descriptions are identical, otherwise False
