The correct solution is to abandon texture using the old, broken noise
function and adjust textures accordingly. You should not count on
POV-Ray supporting every broken feature forever. Future versions of
POV-Ray could just change the default textures to compensate for the
changed noise functions and then, while not looking identical, the
texture will look similar. Of course, this is a one-time inconvenience,
but fixing it once properly is far better than just patching around it.
