[Ldsoss] AntiAlias Java

[Jay Askren]

I tried your code on version of 1.5_04 of java and it didn't work.
SwingUtilities2 is not mentioned in the javadocs for Java 1.5, so I looked
at the code for SwingUtilities2 source code, and it appears that
SwingUtilities2 is not stable, and the the comments said to not rely on the
class.

I did find the following links:

http://forum.java.sun.com/thread.jspa?threadID=700404&messageID=4064797


So it looks like at least for now using the RenderingHints might be a bit
more robust though I haven't tried it.  It should work with Java 1.4.
