Yes, but the drawing functions ultimately inherit the error codes from
FT_Glyph_To_Bitmap currently. Therefore it has to be something
different from those defined in fterrdef.h to distinguish. It would be
good if freetype reserved an FT_Err_User, defined as -1 or 0xFF
perhaps, which is not yet taken.
