[Paraview] question about points size

[Dominik Szczerba]

I wonder how PointSize is implemented in representation->points in ParaView.

Is it achieved with vtkGlyphSource2D/Vertex and setting the glyph size?

It works neatly in PV but I must achieve a similar effect using VTK and 
despite setting glyph size I always get a tiny pixel.

When I use vtkGlyphSource2D/Square it works, but then the square glyphs are 
not always aligned with the viewing plane.

Any hints are very appreciated.
