It is pretty easy, all libraries as freetype, cairo, libxft are allready patched with all that LCD-cleartype-subpixel-autohint stuff. We need just turn it on, because they are disabled by default. Just adjust symlinks in /etc/fonts/conf.d to apropriate files in /etc/fonts/conf.avail - look at left pane in mc to see what should be symlinked.
Here you can compare default rendering to MS Windows rednering, windows fonts doesn't look good, shapes and size are wrong.
After symlinking correct settings they now apear very close to windows rendering.
Another screenshot with font settings window as I like it.
