Allocate resources for the lookup table and the volume on the GPU. Prerequisite: SetImage and SetcolorTable has been called.
Call this from inside a PrepareForRendering() methods in vtk.
Implemented in cx::GPUImageLutBufferImpl.

If data is changed, send data to GPU.Activate and bind the volume and lut buffers inside the texture units GL_TEXTURE<2X> and GL_TEXTURE<2X+1>. Use during RenderInternal()
Implemented in cx::GPUImageLutBufferImpl.
