Разработчики FreeType порадовали.
/**************************************************************************

* Uncomment the line below if you want to activate LCD rendering
* technology similar to ClearType in this build of the library. This
* technology triples the resolution in the direction color subpixels. To
* mitigate color fringes inherent to this technology, you also need to
* explicitly set up LCD filtering.
*
* Note that this feature is covered by several Microsoft patents and
* should not be activated in any default build of the library. When this
* macro is not defined, FreeType offers alternative LCD rendering
* technology that produces excellent output without LCD filtering.
