[ft] *.otf support in version 2.3.5

[Govind]

Hi,

I tried some *.otf files with Freetype_2.3.5 version for Bitmap Glyph generations.
But  API :
         FT_New_Face (library, filename, 0, &face);
         returns FT_unknown_File_Format error message i.e. error code 2.

Same Freetype project version is working fine with almost all *.ttf(true type font) files.
Can I have support for *.otf  font files with above mentioned version of Freetype.
Is there, any specific project or API calling settings required for *.otf files ?

Thanks and Regards
Govind.
