Detailed Description

+A 4*4 Homogenous Matrix. +

+This is a column matrix, so operations like: v1=A*B*C*v0; applies C first , then B, then A to vector v0.
+ Since it is a column matrix, the first column is the I vector of the base, 2nd is J, 3th is K.
+ 4th column vector is T, the translation vector. +

+Angle orientation are: Xaxis: YtoZ. Yaxis: ZtoX. Zaxis: XtoY. +

+This matrix keep a matrix state to improve Matrix, vector and plane computing (matrix inversion, vector multiplication...). The internal matrix know if:

matrix is identity
matrix has a translation component
matrix has a rotation component
matrix has a uniform scale component (scale which is the same along the 3 axis)
matrix has a non-uniform scale component
matrix has a projection component (4th line of the matrix is not 0 0 0 1).

+An example of improvement is that CMatrix::operator *(const CVector &v) return v if the matrix is identity. +

+By default, a matrix is identity. But for a performance view, this is just a StateBit=0...

+Explicit setup the Rotation/Scale matrix (base). +
+Avoid it. It implies low compute since no check is done on m33 to see what type of matrix it is (identity, raotation, scale, uniform scale)
+Parameters:

m33 + + the 3*3 column rotation matrix. (3x3 matrix stored in column-major order as 9 consecutive values)
hintNoScale + + set it to true if you are sure that your rot matrix is a pure rot matrix with no scale. If set to true and your rotation is not an orthonormal basis, unpredictable result are excepted.
