transform method
Transform arg
of type Vector2 using the transformation defined by
this.
Implementation
Vector2 transform(Vector2 arg) {
final argStorage = arg._v2storage;
final x = (_m2storage[0] * argStorage[0]) + (_m2storage[2] * argStorage[1]);
final y = (_m2storage[1] * argStorage[0]) + (_m2storage[3] * argStorage[1]);
argStorage[0] = x;
argStorage[1] = y;
return arg;
