Method byTransforming

src/main/java/field/graphics/FLine.java:1442–1458

make a new line by transforming all of the positions of this line by a function. 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 th
