0024393: Visualization - objects position with enchanced precision
Graphic3d_ZLayerSettings - public fields have been replaced by methods. Added new property Origin defining local coordinate system for all Layer objects. Syntax of Draw Harness command VZLayer has been redesigned. Graphic3d_CStructure now stores bounding box with double precision floats. OpenGl_BVHTreeSelector - frustum culling now works with double precision floats.
