0029295: Visualization, TKOpenGl - provide distance culling option

Browse Source 
Graphic3d_ZLayerSettings::CullingDistance() and ::CullingSize() - added
new properties configuring culling of small and distant objects, disabled by default.
OpenGl_BVHTreeSelector now handles size culling and distance culling in addition to frustom culling.
