Function mulV2

mulV2(m: Mat3, a: Vec2, b: Vec2): Vec2
b = m * a

Multiplies the 3x3 matrix m by the 2-element column vector a and stores the result in the 2-element vector b.

This is a convenience function where m is assumed to be a 2D transformation matrix and a implicitly represents the homogeneous coordinates [ a.x, a.y, 1.0 ]
Parameters
- m: Mat3
  the 3x3 matrix multiplication operand
- a: Vec2
  the 2-element vector multiplication operand
- b: Vec2
  a 2-element vector in which to store the result
Returns Vec2
b as the result of m * a
