[Pharo-dev] FreeType hinting: any way to get a grayscale version for the subpixel rendering?

Is there a way to hint without having the subpixels rendered with the RGB artifacts? Just getting grayscale for the font? I ask because it is getting disturbing for me with larger fonts. I saw some monoHinting in FreeTypeSettings but there doesn't seem a way to set that up. TIA Phil
