multipage pdf -zoom options broken
The commit "bgo#760262: rsvg-convert: Actually scale the image if required" 7db196ea
raised a regression: the zoom aggregates on following pages, it's not reset
Steps to reproduce: The following command puts page.svg four times in a pdf file
rsvg-convert -f pdf -o pages.pdf -z 0.8 page.svg page.svg page.svg page.svg page.svg
result: page 1 is ok, but following pages become smaller and smaller and smaller.
