+% x, y - Coordinates at which to draw text.
+% strings - An array of strings, one for each line of the text item,
+% in order from top to bottom.
+% spacing - Spacing between lines.
+% xoffset - Horizontal offset for text bbox relative to x and y: 0 for
+% nw/w/sw anchor, -0.5 for n/center/s, and -1.0 for ne/e/se.
+% 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.
+% stipple - Boolean value indicating whether or not text is to be
+% drawn in stippled fashion. If text is stippled,
+% procedure StippleText must have been defined to call
+% StippleFill in the right way.
+%
+% Also, when this procedure is invoked, the color and font must already
+% have been set for the text.
