[type1, cid] Add hinting engine switch.
Implement property service in `type1' and `cid' drivers to allow
switching between FreeType or Adobe hinting engine when both are
available.
* src/cid/cidriver.c (cid_property_{set,get}, cid_services),
src/type1/t1driver.c (t1_property_{set,get}, t1_services): Add
Properties service.
* src/cid/cidobjs.c (cid_driver_init), src/type1/t1objs.c
(T1_Driver_Init): Add default property values.
