+	The movie holds the image as a series of vertical strips, say 16 or 32 pixels wide.
+
+	The panorama bounds defines the entire panorama. The view bounds represents the
+	area on the panorama that is kept in memory.
+
+	The panorama bounds is also stored in the movie file; it cannot be changed. The
+	view bounds must always be a subset of the panorama bounds.
+
+	In actuality, the area kept in memory is at least as wide as the view bounds (but
+	may be wider to coincide with the width of the movies slices), and is as tall as
+	the panorama bounds. The view bounds is used by the drawPanorama function to draw
+	a piece of the panorama to the current screen.
+
+	The panorama movie is built at a time scale of 1, with each strip lasting for one
+	second, so that strip number corresponds exactly with the time value at which the
+	strip is stored.
+
+	TO USE:
+
+	Call one initFromMovieFile to open the movie. Then set up a view rect by
+	calling setViewBounds. Once these two functions have been called, drawPanorama
