Creates a grayscale gradient transition defined by two custom points in a circular fashion. The transition is not from a to b, but rather as a revolution around the first point, starting and ending at the second point. Keep in mind results will never tile.
Parameters
Point 1: First point to revolve the gradient around, does not have to be centered
Point 2: Second point for gradient to start and end at.
Non Square Expansion: False/True Enable compensation of squash and stretch with non-square ratios.
