0026392: Visualization, TKD3DHost - provide straight-forward base for integration of TKOpenGl viewer into D3D-based application

Browse Source 
D3DHost_GraphicDriver - new graphic driver providing D3D host for OpenGL workspace.
WNT_Window - handle virtual dimensions within virtual window.
OpenGl_FrameBuffer::Init() - add protection against 0 dimensions.
V3d_View::IsInvalidated() - add method to check view cache validation state.

ViewerTest::ViewerInit() - create virtual window without decorations on Windows.
