Multiplies a vector's x, y, and z components.
mult() can use separate numbers, as in v.mult(1, 2, 3), another p5.Vector object, as in v.mult(v2), or an array of numbers, as in v.mult([1, 2, 3]).
If only one value is provided, as in v.mult(2), then all the components will be multiplied by 2. If a value isn't provided for a component, it won't change. For example, v.mult(4, 5) multiplies v.x by, v.y by 5, and v.z by 1. Calling mult() with no arguments, as in v.mult(), has no effect.
The static version of mult(), as in p5.Vector.mult(v, 2), returns a new p5.Vector object and doesn't change the originals.
