* While FreeType's PCF driver doesn't expose API functions by itself,
* it is possible to control its behaviour with @FT_Property_Set and
* @FT_Property_Get. Right now, there is a single property
* `no-long-family-names' available if FreeType is compiled with
* PCF_CONFIG_OPTION_LONG_FAMILY_NAMES.
*
* The PCF driver's module name is `pcf'.

* @property:
* no-long-family-names
*
* @description:
* If PCF_CONFIG_OPTION_LONG_FAMILY_NAMES is active while compiling
* FreeType, the PCF driver constructs long family names.
*
* There are many PCF fonts just called `Fixed' which look completely
* different, and which have nothing to do with each other. When
* selecting `Fixed' in KDE or Gnome one gets results that appear rather
* random, the style changes often if one changes the size and one
* cannot select some fonts at all. The improve this situation, the PCF
* module prepends the foundry name (plus a space) to the family name.
* It also checks whether there are `wide' characters; all put together,
* family names like `Sony Fixed' or `Misc Fixed Wide' are constructed.
*
* If `no-long-family-names' is set, this feature gets switched off.
*
* {
* FT_Library library;
* FT_Bool no_long_family_names = TRUE;
*
*
* FT_Init_FreeType( &library );
*
* FT_Property_Set( library, "pcf",
* "no-long-family-names",
* &no_long_family_names );
* }
*
* @note:
* This property can be used with @FT_Property_Get also.
*
* This property can be set via the `FREETYPE_PROPERTIES' environment
* variable (using values 1 and 0 for `on' and `off', respectively).
