Fog of war line type for drawing.#707

a line type for drawing shapes that would be considered for line of sight calculations for fog of war. could be its own tool type, or part of the drawing tool. this would be handy for those of us that still draw maps in real time rather than use 3d objects or just use flat maps imported as a board.

I would love this as well. I typically import maps as Custom Boards, then end up adding 3d walls to the 2d map out of necessity when it would be nice to be able to just draw in lines to block line of sight. It would be a much faster alternative and likely have less issues with line of sight clipping through like I run into with some wall models.
