			*
			* @return:
			* FreeType error code. 0~means success.
			*
			* @note:
			* Due to *PATENTS* covering subpixel rendering, this function doesn't
			* do anything except returning `FT_Err_Unimplemented_Feature' if the
			* configuration macro FT_CONFIG_OPTION_SUBPIXEL_RENDERING is not
			* defined in your build of the library, which should correspond to all
			* default builds of FreeType.
