Summary feColorMatrix calculation for type matrix does not incorporate channel offsets

In FEColorMatrix.cpp, the 'offset' matrix values (the fifth column in the matrix) are not used to calculate the result of a color transformation. The correct matrix multiplication is stated here: http://www.w3.org/TR/SVG/filters.html#feColorMatrixElement.
