[RootLayerScrolls] New baselines for printing tests.

The text diffs are due to the new layer tree structure.  The image
diffs are only on Win10, and they appear to be shading differences
due to antialiasing.  Most likely, this is caused by floating point
numerical differences when the printing code applies a zoom factor
to the page.
