This patch makes the background grid of the node editor a grid of dots instead of lines. This makes the background look a bit more subtle and reduces visual complexity. The dots are meant to provide a reference when panning and zooming. Based on the design of @pablovazquez, and a patch originally authored by @fabian_schempp. The "Grid Levels" controls how many levels of dots are drawn. As the editor zooms in, the higher levels of dots fade in, making them closer together visually. The zoom factor at which each grid starts and ends fading in is controllable in the code, and could be tweaked further in the future. The new default value is 7, out of a range from 0 to 9.
