Multiple PrsMgr_PresentableObject::Compute() methods have been replaced by single one PrsMgr_PresentableObject::computeHLR(). Dummy implementations of previously declared methods have been removed from AIS classes not implementng HLR presentation. Class Prs3d_Projector has been removed and Graphic3d_Camera is now passed directly, so that redundant dependency from HLRAlgo_Projector in Prs3d interfaces has been eliminated. StdPrs_HLRShape and StdPrs_HLRPolyShape now implement common interface StdPrs_HLRShapeI.
