tdf#128212 Change the text z camera rotation order.

Old order:
1) Apply all rotation values (normal and camera z)
2) Do the adjustment (top, middle, bottom)

New Order:
1) Apply rotation values except camera z
2) Do the adjustment (top, middle, bottom)
3) Apply camera z rotation.

We rotate the text at the center of the already positioned rectangle
of the text, which depends on e.g. the length of the laid out text.
This matches the PowerPoint behavior.
