   widget (mostly a gtkfixed widget), then 0,0 is send.
   If the mouse is on the top-left pixel of the container widget then the
   coordinates can be negative, if there is frame around the client area.
-  
-  The algorithm:
-  1. the gdkwindow of the message is determined (MsgGdkWindow).
-  2. the gdkwindow of the client area is determined (=ClientGdkWindow).
-  3. the relative position of the client gdkwindow and the message gdkwindow
-     is calculated (MsgClientRelPos).
-  4. Substracting the MsgClientRelPos from the mouse coordinates results in
-     the mouse coordinates relative to the client gdkwindow.
