 Default constructor.

 Reset matrix to unity.

 Reset matrix to zero, only the perspective scaling is set to w
 (1 by default).

 Reset rotation part of the matrix to unity.

 Set matrix from another,

 Set matrix from Double_t array.

 Set matrix from Float_t array.

 Setup the matrix as an elementary rotation.
 Optimized versions of left/right multiplication with an elementary
 rotation matrix are implemented in RotatePF/RotateLF.
 Expects identity matrix.

 A function for creating a rotation matrix that rotates a vector called
 "from" into another vector called "to".
 Input : from[3], to[3] which both must be *normalized* non-zero vectors
 Output: mtx[3][3] -- a 3x3 matrix in colum-major form

 Multiply from left: this = t * this.

 Multiply from right: this = this * t.

 Copy, multiply from right and return product.
 Avoid unless necessary.

 Transpose 3x3 rotation sub-matrix.

 Move in local-frame along axis with index ai.

 Rotate in local frame. Does optimised version of MultRight.

 Move in parent-frame along axis index ai.

 General move in parent-frame.

 Rotate in parent frame. Does optimised version of MultLeft.

 Move in a's coord-system along axis-index ai.

 into i2.

 Sets Rotation part as given by angles:
 a1 around z, -a2 around y, a3 around x.

 Sets Rotation part as given by angles a1, a1, a3 and pattern pat.
 Pattern consists of "XxYyZz" characters.
 eg: x means rotate about x axis, X means rotate in negative direction
 xYz -> R_x(a3) * R_y(-a2) * R_z(a1); (standard Gled representation)
 Note that angles and pattern elements have inversed order!

 Implements Eulerian/Cardanian angles in a uniform way.

 Get Cardan rotation angles (pattern xYz above).

 Scale matrix. Translation part untouched.

 Remove scaling, make all base vectors of unit length.

 Norm 3-vector in column col.

 Orto-norm 3-vector in column col with respect to column ref.

 Orto-norm columns 1 to 3.

 Invert matrix.
 Copied from ROOT's TMatrixFCramerInv.

 Stream an object of class TEveTrans.

 Print in reasonable format.

 Initialize from array.

 Initialize from TGeoMatrix.

 Set TGeoHMatrix mat.

 Fill transformation part TBuffer3D core section.

 Test if the transformation is a scale.
 To be used by ROOT TGLObject descendants that potentially need to
 use GL_NORMALIZE.
 The low/high limits are expected to be squares of acutal limits.

 Ideally this should be done by the TGLViewer [but is not].
