% yoffset - Vertical offset for text bbox relative to x and y: 0 for
% nw/n/ne anchor, +0.5 for w/center/e, and +1.0 for sw/s/se.
% justify - 0 for left justification, 0.5 for center, 1 for right justify.

% drawn in stippled fashion. If text is stippled,
% procedure StippleText must have been defined to call
