Add a more complex test for a PDF saving bug

Add a second PDFEditImgTest case to further demonstrate a PDF saving
bug, where a no-op FPDFPageObj_SetMatrix() call causes the saved PDF to
have incorrect transformation matrices. This second test case has an
image inside a form. This test also demonstrates FPDFPageObj_GetMatrix()
behavior and shows what the matrix is relative to. Mention this in the
API's documentation.
