[vtkusers] Textured Isosurfaces

[Lisa Avila]

Hello Everyone,

I am modifying volume rendering in VTK to support multiple-component data 
which may be independent fields or may represent something like RGBV or LV 
(where V becomes A after being passed through a LUT).

The issue is that VTK currently supports the notion of a texture applied to 
the volume, but the only mapper that supports this is the ray cast mapper 
when used with an isosurface ray function. I would like to yank this 
texture input and parameters, since the functionality will now be provided 
through multiple component data. This will be an API change for anyone 
using this functionality right now. My suspicion is that no one is using 
this and it is OK to change. Anyone disagree?
