class  Graphic2d_TransientManager
 This class allows to manage transient graphics
above one View.
A simple way to drawn something very quicly above
a complex scene (Hilighting,Sketching,...)
All transient graphics will be erased at the
next View::Update(),Redraw().

Remember that nothing is stored by this object and
graphic library,the application must managed itself
exposure,resizing,...

The double_buffering must be is activated on the view,
the back buffer is preserved and used for restoring
the front buffer at begin drawing time.
