[Paraview] Exporters in Paraview GUI

[clinton at elemtech.com]

I don't know of a simple or direct way to do that.

But it might be possible to do with a plugin that implements a custom view, 
instead of a writer.

http://www.paraview.org/Wiki/Plugin_HowTo#Adding_a_custom_view

The only parts you'd need are to define a ViewModuleProxy in the server 
manager xml, and on the client side, make your own view class derived from 
pqRenderView.  You'll notice the example has a captureImage() function, and 
that's about where you can put your exporters that require a vtkRenderWindow.  
In that client code, you can define your own context menus for the view if 
you wanted to use that to let the user a choose which exporter to use.  You 
could also add checks in there to make sure rendering is done on the client 
side, which some of those exporters seem to require.

The cmake macro ADD_PARAVIEW_VIEW_MODULE only requires the VIEW_TYPE and 
VIEW_XML_GROUP, which is all that plugin would define.
