UV's are a Vector4 so that 3D texture volumes can be supported.
They're not currently but it seemed prudent to not design in a
limiting factor to the uv attribute. It also matches OpenGL.
Just set Z to 0, it should be ignored by the current shading system.
fwiw the ordering of the vector is defined in the Vector4.h header
file - x,y,z,w.
Ok Jonathan thanks for the explanation! What would we all do without
your insights :-)
I wonder what Is the W doing here - normal direction override?..
