Show bigger preview for inpaint and smaller brush

If you currently use inpaint, the preview pictures are really small. So if you want to inpaint some small detail (fingers, eyes, lips...) you have to use the browser zoom to acutally see what you are painting (with a quite big brush even on the smallest setting). The browser zoom works until 200% and even then some previews are still to smal to inpaint named details. If you go above 200% browser zoom the inpainted area will not stay where you painted it in, but move as soon as you zoom out.

TL;DR: give us bigger preview pictures and smaller brushes
