Fix incorrect current transformation matrix when saving PDFs

CPDF_PageContentGenerator has been incorrectly writing out the inverse
of the current transformation matrix when saving PDFs, instead of the
CTM. The reason this worked for many test cases is because they tested
PDFs where the inverted CTM is equal to the CTM. With new test cases
where the inverted CTM is not equal to the CTM, making this correction
makes them render correctly.
