+/**
+   This class creates from a given X11 Window a special image to
+   display.
+   An image has some characteristics, like startadress, width height,
+   if each row has a terminating modifier etc...
+
+   The image is resposible for the conversion from the yuv
+   format to the destination.
+
+   It is initialized with the constructed x11Window.
+   During a mode-switch (which is handled by x11window) the following
+   sequence is called:
+
+   support()   ->true/false  if this image type is supported
+                             (switching to it is allowed)
+
+   openImage()               called once when we switch to this
+                             image type
+
+   ditherImage(..)           for the conversion from yuv->rgb
+                             obviously called for every image
+   putImage(..)              time for display it
+
+   closeImage()              called once, when we leave this image type
+
+
+   This sequence is necessary, because the user likey to switch
+   form desktop display to dga fullscreen.
+   
+   The following image classes seems to be useful:
+
+   imageDeskX11   : standard ximage, maybe with shared mem support
+                    full software rendering
+   imageDeskXV    : image with hardware yuv->rgb rendering
+
+   imageDGAFull   : dga 2.0 full software rendering (needs root)
+   imageXVFull    : fullscreen hardware yuv->rgb rendering
+
+   The hierarchy is as follows:
+
+   (desk mode)
+   imageStdX11  : fallback, should work everywhere
+   imageStdXV   : if supported imageStdX11 is disabled
+
+   (fullscreen mode)
+   imageDGAFull : 
+   imageXVFull  :
+		   
+   The supported switches between the modes are
+
+
+   desktop          <->         fullscreen mode.
