// The depth range is handled in the vertex shader. We need to reverse
// the far value to get a reversed depth range mapping. This is necessary
// because we have the most precision at the near plane, while the console
// has the most percision at the far plane.
// because the standard depth range equation pushes all depth values towards
// the back of the depth buffer where conventionally depth buffers have the
// least precision.
