	 * For example `someLine.byTransforming( (p) => p + vec(10,0) )` will yield a line 10 units to the right of `someLine` (of course `someLine + vec(10,0)` does the same). You might need a
	 * little more JavaScript syntax than usual here: `someLine.byTransforming( function(x) { ... return something ... } )` and `someLine.byTransforming( (x)=> { ... return something ... } ) `
