+
+  To create an animation bitmap you need to place the different
+  frames in a horizontal layout. Each frame must be the same size.
+  I included the original gears.xcf file which can be edited with 
+  'The Gimp' imaging program.
+  
+  This demo includes two animation examples.
+  
+    gears.bmp - which contains 4 frames with transparency.
+    wanda.bmp - which contains 8 frames and no transparency.
+                Wanda the fish originates from the Gnome project.
