VIS - Exception when trying to display some surfaces using iVtk with VTK 9
Description
Visualization of some surfaces (such as Sphere, Torus, Cone with apex) leads to an exception, when trying to display it via iVtk. This problem appeared after upgrade to VTK 9, cause vtkPolyData and vtkCellData were strongly reworked.
Problem is located in IVtkTools_SubPolyDataFilter::RequestData(), and is caused by incorrect memory allocation in anOutput->Allocate(anInput, anIdList->GetNumberOfIds()) with an exception in anOutput->CopyCells (anInput, anIdList) when trying to insert a cell to unallocated array.
It seems this is a REGRESSION in VTK itself caused by incorrect rounding math.

+#if (VTK_MAJOR_VERSION > 8)
'VTK_MAJOR_VERSION >= 9' would look more clear.

Memory allocation for VTK versions 9 and above was updated according to changes in vtkPolyData.
Build/test results for Windows can be found at
http://jenkins-test-occt/view/CR32331-master-vtk9/
Unfortunately VTK 9 fails to be built on jenkins, seems like it has some issues with Debian 8. Igor was able to build it manually on Debian 10 and all tests went fine. Customer behind this issue uses Debian 10, so this should suffice.
