Summary
Sets the values of the specified L_MATRIX structure to identity.

L_LTKRN_API L_VOID L_Matrix_Identity(matrix)
Parameters
L_MATRIX* matrix
Pointer to the L_MATRIX to test.
Returns
None.
Comments
An identity matrix has a value of 1 in coefficients [1,1],[2,2],[3,3] and a value of 0 in the rest of the coefficients. This correlates to setting m11 and m22 to 1 and m12, m21, offsetX, and offsetY to 0.
In an affine matrix, coefficients [3,1],[3,2],[3.3] are implied to always have the values 0,0,1 respectively.
