move in center of radial_gradient_precision
{1K,1K} ought to work fine for F16 precision. 16 bit floats step by 1.0
between 1024 and 2048, so they should be able to just barely represent
distinct coordinates for each pixel. If precision drops below 16 bit
we'll start seeing banding because we can't distinguish coordinates.
Swap out the colors a little so that it's clear which images are the 1K
(black+green) and which are the old 100K (black+white).
