Summary0023494: Picker operates worse on transformed Data Source
DescriptionThe attached main function illustrates usage of VIS Shape Picker on initially transformed OCCT Topological Shape. There are two simple pipelines in the attached example:

Main pipeline (representing OCCT shape):
  Data Source -> Mapper

Highlighting pipeline:
  Data Source -> Sub-shapes filter -> Mapper

No additional VTK filters are used here. The problem is that VIS picker sometimes stops working depending on the shape's location:

1. Start main function;
2. Press "r" key for fitting;
3. Try picking the displayed shape: faces are picked correctly (see the log window and highlighting in 3D);
4. Click right mouse button for applying different (random) transformations on the initial TopoDS_Shape (the corresponding polygonal source is rebuilt from scratch). Try picking for each new position:

===> BUG: sometimes picker stops working.

The workaround for this issue is re-construction of picker on each click event.
