Applies color transformation to an image. This method permits
saturation changes, hue rotation, luminance to alpha, and various
other effects. Although variable-sized transformation matrices can
be used, typically one uses a 5x5 matrix for an RGBA image and a 6x6
for CMYKA (or RGBA with offsets). The matrix is similar to those
used by Adobe Flash except offsets are in column 6 rather than 5
(in support of CMYKA images) and offsets are normalized
(divide Flash offset by 255)
