Ben we were testing LabelShieldTest with a pure java implementation of
PerceptualDiff.
Looking at the visual comparison this test is very sensitive to different
fonts used, as a large box is drawn around the output). Since we are using
a generic "serif" font for the test we are ensured different "default"
results between platforms.
For details on logical (i.e. platform specific) vs physical fonts
http://docs.oracle.com/javase/tutorial/2d/text/fonts.html
Looks like we should change our test to use "Lucidia" fonts.
