*	Some geom2d changes.	Robert Vollmert	2009-11-01	1	-2/+6
\| \| \| \| \|	1. Add function to reflect vector at a line. 2. Implement scalar multiplication as external operator.
*	Make nextcell and movehalfcell methods of geom::ray.	Robert Vollmert	2009-11-01	1	-2/+3
\| \| \| \| \|	Seems sensible given they modify the ray, even if it's not really something intrinsic to a ray.
*	Change corner handling.	Robert Vollmert	2009-11-01	1	-1/+2
\| \| \| \| \| \| \| \|	ray_def should now deal with hitting corners gracefully, though the raycasting will still discard such rays. If a ray hits a corner between two diamonds, it will stay there, and calling ray_def::pos will arbitrarily give one of the squares -- this is not optimal, but these rays shouldn't usually show up anyway.
*	Add simple 2d geometry library.	Robert Vollmert	2009-11-01	1	-0/+84
	Its point is to allow intersecting rays with grid lines and advancing rays from one cell to the next.
