Tiling tool for wallpaper, radial and line tiling

The current tiling mechanism is quite powerful, but quite confusing to use. This tiling tool proposal uses an on-canvas approach where users define the output through the editing of a "render frame" with a "base tile." Dynamics can be defined on-canvas as well. This tool also extends the tiling functionality towards radial and "line" tiling (an extension for Pattern along Path).
