class Window from WNT inherits Window from Aspect
---Purpose: This class defines Windows NT window
-- Warning: The position and size for the creation of the window
-- are defined in Device Screen Unit (DSU)
-- floating [0,1] space.
--
-- As 3D view window is the main purpose of this class,
-- and 3D view does not need its background to be drawn
-- by the system, by default the window background is not drawn.
-- This can be overridden by calling ClearFlags( WDF_NOERASEBKGRND ).
-- See also WNT_WndProc.cxx and InterfaceGraphic_WNT.hxx.

---Purpose: Creates a Window defined by his Center and his Size

-- The smaller dimension of the window is limited to 1.0
-- We can give a value greater than 1.0 to the larger
-- dimension.
-- No matter how large the values passed in argument, the
-- window is automatically limited to the maximum size of
-- the screen.
-- The ratio of width to height of a conventional screen is
-- of the order of 1.3.
-- Trigger: Raises WindowDefinitionError if the Position out of the
-- Screen Space or the window creation failed.
