[Paraview] problem with Glyph filter using Python scripting

[Utkarsh Ayachit]

Hello Sylvester/Roland,

Oepn at Servers/ServerManager/filters.xml and look at the xml for the 
"Glyph" filter. You'll notice that the "Source" property has a domain 
named "proxy_list" which lists the names of the proxy types the GUI can 
allow the user to choose. When the glyph filter is created by the GUI, 
the GUI iterates over all these types, create new proxy instances for 
each and adds then to the domain using 
"vtkSMProxyListDomain::AddProxy()". The panel the simply goes through 
the list and shows them in the "Glyph Type" combo box.

So here the fix your python script:

...

source = servermanager.sources.GlyphSource2D(GlyphType=8)
glyph = servermanager.filters.Glyph(Input=elev,
Source=source,registrationGroup="sources",registrationName="glyph")
sourceProperty = glyph.GetProperty("Source")
domain = sourceProperty.GetDomain("proxy_list");
domain.AddProxy(source.SMProxy)

...
