public delegate Blob ReferenceTableFunc (Face face, Tag tag)
Callback function for create_for_tables.
The tag is the tag of the table to reference, and the special tag HB_TAG_NONE is used to reference the blob of
the face itself. If referencing the face blob is not possible, it is recommended to set hb_get_table_tags_func_t on the face
to allow reference_blob to create a face blob out of individual table
blobs.
