+top of included graphics.  The LaTeX material may also be rotated and typeset
+on top of a white box overshadowing the graphics.  The coordinates of the
+LaTeX boxes are given relative to the original, unscaled graphics; when the
+graphics is rescaled, the LaTeX annotations stay at their right places (unless
+you do something extreme).  In a draft mode, the package enables you to draw
+a coordinate grid over the picture for easy adjustment of positions of the
+annotations.")
