Patterns like bumps/bozo/spotted, leopar, granite, wave/ripples and
agate seems to use a sin like distribution.
Patterns like gradient, onion, radial, boxed, spherical, planar,
cylindrical and spherical use a ramp, or linear, distribution.
wood use a triangular distribution.
You can always use a different wave type if you want.
When you just want to view some colour_map, it's bettrer to stick to the
linear ones.
