Function rotate

rotate<T>(m, angleInRadians, dst?): T
Rotates the given 3-by-3 matrix by the given angle.
Type Parameters
- T extends BaseArgType = number[]
Parameters
- m: BaseArgType
  The matrix.
- angleInRadians: number
  The angle by which to rotate (in radians).
- Optional dst: T
  matrix to hold result. If not passed a new one is created.
Returns T
The rotated matrix.
