 //      Input: matrix       ; a 4x4 matrix
 //      Output: translation ; a 3 component vector
 //              rotation    ; Euler angles, represented as a 3 component vector
 //              scale       ; a 3 component vector
 //              skew        ; skew factors XY,XZ,YZ represented as a 3 component vector
 //              perspective ; a 4 component vector
-//      Returns false if the matrix cannot be decomposed, an object with the above output values if it can
-//
-//        Supporting functions (point is a 3 component vector, matrix is a 4x4 matrix):
-//          float  determinant(matrix)          returns the 4x4 determinant of the matrix
-//          matrix inverse(matrix)              returns the inverse of the passed matrix
-//          matrix transpose(matrix)            returns the transpose of the passed matrix
-//          point  multVecMatrix(point, matrix) multiplies the passed point by the passed matrix
-//                                              and returns the transformed point
-//          float  length(point)                returns the length of the passed vector
-//          point  normalize(point)             normalizes the length of the passed point to 1
-//          float  dot(point, point)            returns the dot product of the passed points
-//          float  cos(float)                   returns the cosine of the passed angle in radians
-//          float  asin(float)                  returns the arcsine in radians of the passed value
-//          float  atan2(float y, float x)      returns the principal value of the arc tangent of
