Added a method mul()

[paperschool]

This method is for simple multiplication of two vectors

Can you give an example of where/how this would be used? I haven't really had a use for vectors multiplied this way.

(I think this is called a Hadamard Product)

[paperschool]

Its an obscure one for sure, usually id use this kind of calculation when applying some kind of friction vector to an velocity vector before applying it to a player position rather than manually multiplying the x's and y's. eg

playerVel.mul(playerAcc);
playerVel.mul(worldFriction);
playerPos.add(playerVel);

Naturally an incomplete description but i think I made the point, also I think I may have made a typo anyway in the function if you do accept it.

Ah, I think you can do this with the existing scale function (The only difference is that it doesn't directly take in a vector parameter, but individual x and y parameters):

vel.scale(acc.x, acc.y)
vel.scale(friction.x, friction.y)
pos.add(vel)

Given that it's pretty easy to accomplish this by using the scale method, I'm going to close this.
