[Paraview] using Point Sprite from python

[Sergei D.]

Hi.
Please, tell me where can I find info about using plugins from python?
I use LoadPlugin() for ParaView-3.7 and for 3.6.2 but without result:
plugin is loaded without errors, but not visible:

In [8]: LoadPlugin
('/opt/ParaView-3-6-2-rc1/bin/plugins/CSCS_PointSprite_Plugin/libCSCS_PointSprite_Plugin.so',globals())

In [9]: Sphere()
Out[9]: <paraview.servermanager.Sphere object at 0x1d9ab10>

In [10]: dp=Show()
vtkSphereSource : [ ...........]

In [11]: dp.GetProperty('Representation').Available
Out[11]: ['Outline', 'Points', 'Wireframe', 'Surface', 'Surface With Edges']

I.e. Point Sprite representation is not available. Is this a bug or am I
doing something wrong?
