maths: tighten up type requirements for almost_equal
...
almost_equal only operates on two reals, or two integers (and even then
only on the same signedness).

n/fractal: increment fractal pos between octave
...
given summation occurs with only scaling of positions between octaves,
points around the origin are likely to remain self-similar between
octaves. but nudging the point out range of the origin's unit surrounds
we can avoid degenerate highlights.
