SoVolumeData and SoTexture2 GPU composition.

Demonstrates how to combine VolumeData and classical texture using the GPU.

Volume 1 is a medical image (3D head), texture is a mask texture. The data values of the data volumes are multiplied together, causing some portions of volume 1 to become completely transparent. The interesting part of the demo is in the .iv file. The demo just load and display the scenegraph.
