+/**
+ 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.
