The font is buggy indeed since the `ascender' and `descender'
values in the `hhea' table are zero. However, there are valid
ascender and descender values in the `OS/2' table.

It seems to be a good idea to take those values in case `hhea'
data is invalid — BTW, how does this font behave under Windows?

George, David, comments, please.

With Agenda fonts (Agenda-MediumItalic in my case) face->ascender and face->descender are zero. For this reason, face->size->metrics.x_scale and y_scale, calculated by FT_Request_Size with FT_SIZE_REQUEST_TYPE_REAL_DIM are some very large values. Is this a bug in FreeType, or just a broken font ? Font file attached.
