[cairo-commit] cairo/test pdf-surface.c,1.6,1.7

[Carl Worth]

Committed by: cworth

Update of /cvs/cairo/cairo/test
In directory gabe:/tmp/cvs-serv10108/test

Modified Files:
	pdf-surface.c 
Log Message:

        * test/pdf-surface.c: (draw), (main): Update PDF test case to make
        sure we're actually getting the right paper size, image scaling
        etc. And it should now be easier to see if cairo is happy by manually
        viewing the resulting PDF file.
