This removes 3 uniforms, consisting of 9 floats. Those were merged into other values that never get used at the same time. It also moves the costly setup of the fixed colormap out of the render state into the 2D processing code. Since 3D forces use of render buffers now, it is no longer necessary to draw the entire scene with the colormap active, meaning it can be handled more efficiently.
