+/**
+ * Update the mouse sprite info when the server switches from a pScreen to another.
+ * Otherwise, the pScreen of the mouse sprite is never updated when we switch
+ * from a pScreen to another. Never updating the pScreen of the mouse sprite
+ * implies that windows that are in pScreen whose pScreen->myNum >0 will never
+ * get pointer events. This is  because in CheckMotion(), sprite.hotPhys.pScreen
+ * always points to the first pScreen it has been set by
+ * DefineInitialRootWindow().
+ *
+ * Calling this function is useful for use cases where the server
+ * has more than one pScreen.
+ * This function is similar to DefineInitialRootWindow() but it does not
+ * reset the mouse pointer position.
+ * @param win must be the new pScreen we are switching to.
