Assignment to KX_GameObject localOrientation and worldOrientation matrices was assuming row-major matrix although reading these matrices was returning a column-major MathUtils object. The faulty function (PyMatTo) is fixed and all matrices in python are now assumed column-major. This function is also used in the following methods: BL_Shader.setUniformMatrix4() BL_Shader.setUniformMatrix3() (No change in scripts if you didn't specify the optional transpose parameter: the default value is changed so that column-major matrices are assumed as before.) KX_Camera.projection_matrix (assignement to this attribute now requires a column-major matrix and you must fix your script if you were setting a value to this attribute.)
