[OpenJDK 2D-Dev] [9] Review Request: 8167310 The graphics clip is incorrectly rounded for some fractional scales

[Jim Graham]

That does sound like a problem.  Does it do the same thing with new Path2D(Rectangle)?  The Area class does some 
processing on the path and it would be nice to eliminate that as a potential source of this problem.  I don't have a 
buildable JDK9 repo right now that I can fire off some quick tests on so I'll have to look at this later...
