\brief
    Window class intended to be used as a timer. 
    
    
    An application can contains several timer to generate events each count milliseconds. 
    The accuracy of the timer is not accurate enough to do any time counting and is 
    not guaranty either.
    
    This class does no rendering and so appears totally transparent.  This window defaults
    to position 0.0f, 0.0f with a size of 1.0f x 1.0f.
