Detailed Description
specialized shader that uses GLSL to implement a (up-to) 16 bit Hardware Lut
The RGBA LookupTable is loaded into a 2D texture of 256 pixels width and dynamic height. The texture lookups and color interpolation is done with two "assembly" fragment programs, one for bilinear interpolation and one for nearest neigbor interpolation. The shader interacts with the View2DTexture and it's bind message is called by each subtexture that the View2DTexture renders. This is done because the size of the textures changes and this size is needed as local parameters in the fragment program.
