   * @description:
   *    Set a property for a given module.
   *
   * @input:
   *    library ::
   *       A handle to the library the module is part of.
   *
   *    module_name ::
   *       The module name.
   *
   *    property_name ::
   *       The property name.  Properties are described in section
   *       @properties.
   *
   *       Note that only a few modules have properties.
   *
   *    value ::
   *       A generic pointer to a variable or structure that gives the new
   *       value of the property.  The exact definition of `value' is
   *       dependent on the property; see section @properties.
   *
   * @return:
   *   FreeType error code.  0~means success.
   *
   * @note:
   *    If `module_name' isn't a valid module name, or `property_name'
   *    doesn't specify a valid property, or if `value' doesn't represent a
   *    valid value for the given property, an error is returned.
   *
   *    The following example sets property `bar' (a simple integer) in
   *    module `foo' to value~1.
   *
   *    {
   *      FT_UInt  bar;
   *
   *

   *      FT_Property_Set( library, "foo", "bar", &bar );
   *    }
   *
   *    Note that the FreeType Cache sub-system doesn't recognize module
   *    property changes.  To avoid glyph lookup confusion within the cache
   *    you should call @FTC_Manager_Reset to completely flush the cache if
   *    a module property gets changed after @FTC_Manager_New has been
   *    called.

   *       A generic pointer to a variable or structure that gives the
