Rotation angle in radians.

matrix -- returned by the graPHIGS API, 16 short floating-point numbers

Transformation matrix.

The elements are returned in the following order for the transformation matrix:

  |m11 m12 m13 m14|
  |m21 m22 m23 m24| ---> (m11,m12,m13,m14,m21,m22,...m44)
  |m31 m32 m33 m34|
  |m41 m42 m43 m44|
