See the PDF 1.7 specification, Section 8.3.3 ("Common Transformations"). Note: * The PDF format uses row vectors. * Transformations operate from the origin of the coordinate system (PDF coordinates: bottom left corner, Device coordinates: top left corner). * Matrix calculations are implemented independently in Python. * Matrix objects are immutable, so transforming methods return a new matrix. * Matrix objects implement ctypes auto-conversion to ``FS_MATRIX`` for easy use as C function parameter.
