fix(background): make the gradient motions visible at a glance
Measured on a port of the shader, the three motions strayed 3 to 9 % from
the still gradient and changed by less than 1/255 per frame, so they read
as a still background. Motion is now twice as fast and two to ten times
wider, depending on the gradient.
Aurora blobs and wave crests also lighten or darken a little: most offered
gradients pair two neighbouring hues, and moving their own colours alone
stayed invisible on them. Drift slides along its axis on top of swinging
it, since a rotation alone leaves the centre still.1 parent 4dfc09e commit 63e82d3
