density functions

mul multiplies argument1 and argument2 together
add adds argument1 and argument2 together
interpolated does an interpolation of argument
blend_density blends argument to other noises
min takes the smaller value of argument1 and argument2
max takes the larger value of argument1 and argument2
y_clamped_gradient creates a gradient between from_y and to_y spanning between from_value and to_value
old_blended_noise is a 2D noise able to be mapped to 3D
noise is a fancier noise
end_islands is the hardcoded end island noise
shift_a offsets the noise in X and Z
shift_b offsets the noise in X and Y
shift offsets the noise in all directions
clamp applies a minimum and maximum to input
spline applies a spline function to the noise
