 COMMENTS ON PHOTOGRAPHS:
 
 	*  Marker types are displayed wrong,  they should be:
 		Row 1:	.	(point  )
 		Row 2:	+	(plus   )
 		Row 3:	*	(aster  )
 		Row 4:	o	(circle )
 		Row 5:	x	(X      )
 
 	*  For test files marker.v03 and marker.v04  you should
 		notice the effects of perspective on the marker3(s)
 		in the center of each cell.
 
 	*  The text size (for the text at toe bottom of the screen )
 		was reduced from the size on the photograph.  Additional
 		information has been added to that text.
