aba 91d9637224 0027536: Visualization - incorrect behavior of zoom persisted objects
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
