[OpenJDK 2D-Dev] Antialiased horizontal or vertical lines.

Hello.

I noticed that anti aliased horizontal and vertical lines are 
not drawn properly. I've described the results (with pictures)
here: http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=509

In the patch, I try shifting line coordinates by half a pixel as 
soon as they're passed into Renderer.java:lineTo, and it seems to
fix it.

However, this seems a bit too easy, so if anyone can think of any
ways in which this fix breaks something, please let me know.

Thank you,
Denis.
