McCabeism: Fast Multiscale Turing Patterns

This is a variant of Jonathan McCabe's Multiscale Turing Patterns algorithm. It uses a Gaussian neighborhood when computing scale variation densities, split into two 1D Gaussian passes. The original instead uses a uniformly-weighted 2D circular neighborhood. By splitting the neighborhood calculations into two 1D passes the per-pixel complexity of the algorithm is reduced from O(n^2) to O(n), where n is the largest scale parameter. This complexity reduction makes it feasible to render much longer, higher-resolution animations.
