	XII_DECLARE_POD_TYPE ()
void	GetAsArray (float *out_pData, xiiMatrixLayout::Enum layout) const
void	Transpose ()
	Transposes this matrix.
xiiSimdMat4f	GetTranspose () const
	Returns the transpose of this matrix.
xiiResult	Invert (const xiiSimdFloat &fEpsilon=xiiMath::SmallEpsilon< float >())
	Inverts this matrix. Return value indicates whether the matrix could be inverted.
xiiSimdMat4f	GetInverse (const xiiSimdFloat &fEpsilon=xiiMath::SmallEpsilon< float >()) const
	Returns the inverse of this matrix.
bool	IsEqual (const xiiSimdMat4f &rhs, const xiiSimdFloat &fEpsilon) const
	Equality Check with epsilon.
bool	IsIdentity (const xiiSimdFloat &fEpsilon=xiiMath::DefaultEpsilon< float >()) const
	Checks whether this is an identity matrix.
bool	IsValid () const
	Checks whether all components are finite numbers.
bool	IsNaN () const
	Checks whether any component is NaN.

xiiSimdVec4f	TransformPosition (const xiiSimdVec4f &v) const
	Matrix-vector multiplication, assuming the 4th component of the vector is one (default behavior).
xiiSimdVec4f	TransformDirection (const xiiSimdVec4f &v) const
	Matrix-vector multiplication, assuming the 4th component of the vector is zero. So, rotation/scaling only.
