[Paraview] how to modifiy shaders variables / how to use user-written mappers

[Stephane PLOIX]

Hi,

I have some questions about the use of materials and mappers in paraview : 

1 / suppose I have my own material, which use a variable. Take for 
instance the GLSLTwisted material which have a "Rate" variable. How can I 
access/modifiy this variable? 
Can I write some XML file like the ones for user-written filter and 
associate a "vtkSMProperty" to the variable in a server-side xml file, and 
an client-side xml where I describe my interface?
2 / I have written a specific mapper. How can I have acces to this mapper 
in paraview? How could I modify the interface to set specifics of this 
mapper?

Thanks,
Stephane
