The following change appears to make the ThinLineTest pass. I tried a couple
of variations of it, with and without antialiasing, with and without
scaling, and with different scaling factors and line widths. The looked
okay. Btw, bear with me as I am not really a Java 2D person and I may not
know what I'm talking about :) But I got the feeling that the 'thin' logic
(to do with the thin boolean parameter to PiscesRenderingEngine.strokeTo()
and the logic in SunGraphics2D.validateBasicStroke()) isn't compatible with
Stroker.computeOffset().
