[Paraview] Export polydata and texture map in vtk file for viewing in paraview

[James Matthews]

I feel rather stupid for not realising that, thanks for the advice. Ideally 
I'd like to turn off this default behaviour open it in a 3D window.

I am still interested in the original question though, is it possible to 
package polydata and a texture map in a single file so when it is opened you 
see textured mapped geometry, rather than having to import the polydata with 
texture coords and then apply a texture through the display tab?
