+    instances of me can be installed as a viewBackground, 
+    and will draw a gradient background.
+    I can be used as background of color-sliders (HUE, Light, saturation),
+    or for nice looking splashscreens (which was the original motivation for that).
+    
+    More than 2 colors can be specified, all given colors will be visited
+    with a gradient in between each.
+
+    When a view's size changes, I can be configured to either re-adjust my gradient,
+    so that always all colors are visited (but which leads to flicker, because with every
+    resize, the full background needs a redraw),
+    or to always use the screens size as a reference.
+    In the later case, onle new exposed areas need to be redrawn, but only a partial range o colors
+    is drawn.
+
+    See the example, which demonstrates the resizing behavior.
