Description:
The Position of the Background depends on the margins.
It depends on the text-area and not on the page itself.
If I add a picture as a background with the size of the document and set it up it like this:
- Position: center
- Size: Size of the document
- No Tiles
...and the margins are the same size for all 4 sides, everything works fine.
If I change the size of one margin, the background moves and does not fill the whole page anymore.

Steps to Reproduce:
1. Add a picture as a background with the size of the document and set it up it like this:
- Position: center
- Size: Size of the document
- No Tiles
2. Change the margins that at least one differs from the others

Actual Results:
Tha background isn't where it should be

Expected Results:
The background is (and stays) in the center of the page and fills it out completely.

The resolution of the PDF imported as background is getting reduced.
