Face gear (with TOPTION_SHOW_TACTICAL_FACE_GEAR) was offset by one in X and Y compared to the face, probably due to copypasta from portrait icons, causing rendered assets to be shifted and cut off. Most noticeable on gas masks. "GetXYForRightIconPlacement_FaceGera" is only used for face gear, so this offset can be safely removed.
