This is wrong. The hinting style option is independent from sub-pixel rendering.

There are five hinting algorithms in freetype:

- FT_LOAD_TARGET_NORMAL
- FT_LOAD_TARGET_LIGHT
- FT_LOAD_TARGET_MONO
- FT_LOAD_TARGET_LCD
- FT_LOAD_TARGET_LCD_V

But some of them only make sense in combination with other settings, e.g. FT_LOAD_TARGET_MONO would only be used when anti-aliasing is turned off and FT_LOAD_TARGET_LCD_V would imply that sub-pixel rendering is activated and you display is turned vertically (vrgb or vbgr).

The hintingstyle (as in fontconfig/Xft) would then be mapped to one of these hinting algorithms or turn off hinting at all.
