I tried the work around and it look like working with zro degree orientaion. One
thing I undestood is FT_Set_Transform() won't transform the metrics. But using
this how you get this formula is not clear. Please explain. Also please tell me,
is this work around will work for all orientation.

One more query is there please bear with me. When we transform the font image,
we transorm the bimap(buffer only) or we transform the base line also.

Thanks & Regards
