1) Zoom persistence mode now fixes object in pixel coordinates and is independent on view size 2) Used gp_GTrsf instead of gp_Trsf SelectMgr_ViewerSelector to store Graphic3d_Mat4d 3) Zoom persisted objects changed behavior (become bigger) therefore test cases were updated according to new state. 4) Corrected scale for rectangular frustum Updated test for manipulator
