Wave Filter: Add ability to zoom or enlarge the preview pane, and change preview background.

I can't find a solution anywhere, but the preview pane when using Distort > Wave is comically small, even on an ultrawide monitor. I've noticed that other filters within the Distort submenu allow for preview zooming, but not Wave for some reason. To make things worse, the white/gray transparent background preview is extremely noisy at that size, and I would like to see an option added to change the preview background.

Changing my layer to a neon green before running the filter helps ever so slightly, but my steadily declining vision still can't handle how hard it is too see.
