OK, you and James have convinced me to change my mind.
After some thinking I can imagine that the following works.
. Add `FT_FACE_FLAG_TRICKY'. If set, the font is tricky. To access
it, add a macro `FT_IS_TRICKY'. [This is a read-only flag.]
. Change the meaning of `FT_LOAD_NO_HINTING' so that fonts which
always need TrueType instructions (these are fonts which have
FT_FACE_FLAG_TRICKY set) ignore it.
. Instead of adding a new `FT_LOAD_RAW' flag which would do what
`FT_LOAD_NO_HINTING' currently does, I propose that we get the
behaviour of `raw' loading if both `FT_LOAD_NO_HINTING' and
FT_LOAD_NO_AUTOHINT are set.
