Andreas Lehmkühler resolved PDFBOX-646.
---------------------------------------

    Resolution: Fixed

With version 918150 I've added a getter for the optional form matrix of an XObjectForm. Whenever
a XObjectForm has a form matrix it will be took into amount within the Invoke operator by
multiplying it with the current transformation matrix.

Now the attached example works like a charm with the PDFReader.

> An XObjectForm has an optional form matrix to map the form space to user space. If that
matrix is present it has to be multiplied with the current transformation matrix to calculate
the correct coordinates for every following operation.
