Background scaling when zoomed in

The background grid should stay the same when you zoom in, like in other image editors. Maybe use a other image for background as well. For example, the typical grid:

Don't know if this is fixable with current solution. But I tried it now, and I do like it more if the background zooms. I've added an option for this. And I also added: image-rendering: pixelated; so zoomed image does not get smooth edges
