* @property:
* hinting-engine[type1]
*
* @description:
* Thanks to Adobe, which contributed a new hinting (and parsing)
* engine, an application can select between `freetype' and `adobe' if
* compiled with T1_CONFIG_OPTION_OLD_ENGINE. If this configuration
* macro isn't defined, `hinting-engine' does nothing.
*
* The default engine is `freetype' if T1_CONFIG_OPTION_OLD_ENGINE is
* defined, and `adobe' otherwise.
*
* The following example code demonstrates how to select Adobe's hinting
* engine (omitting the error handling).
*
* {
* FT_Library library;
* FT_UInt hinting_engine = FT_T1_HINTING_ADOBE;
*
*
* FT_Init_FreeType( &library );
*
* FT_Property_Set( library, "type1",
* "hinting-engine", &hinting_engine );
* }
*
* @note:
* This property can be used with @FT_Property_Get also.
*
* This property can be set via the `FREETYPE_PROPERTIES' environment
* variable (using values `adobe' or `freetype').
*
* @since:
* 2.8.2
