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

[Jim Graham]

Yes, we do bias both.  So, the code we just added doesn't match the biasing that is performed by the fill operations, we 
should probably make it be the same.  You can see that it computes a bias boolean when it calls getFillSSI(), but the 
bias is applied natively in the native ShapeSpanIterator code...
