Issue of the Implementation # V0031

Brief

FT_Get_PFR_Metrics returns incorrect value for non-PFR fonts

Detailed Description

The description of FT_Get_PFR_Metrics states that
If the input face is not a PFR, this function will return an error.

However if FT_Get_PFR_Metrics is called for a non-PFR font (e.g. FreeMono.ttf) and its other arguments are not NULL, it returns 0 (i.e., no error). The attached example demonstrates this problem.
