Set default graphics before generating page contents

In this CL, the content generator sets some default graphics states
before processing the page objects. In particular, a default ExtGState
is now set before processing, and the last CTM is now stored right
after parsing finishes: the only command to change matrix is ctm, and
it concatenates, so inverting requires knowing the current value.
