[OpenJDK 2D-Dev] Fixes for two bugs in stroker

[Omair Majid]

Hi,

A while ago I filed
http://bugs.openjdk.java.net/show_bug.cgi?id=100046
and
http://bugs.openjdk.java.net/show_bug.cgi?id=100047
which contain fixes for two bugs in lines drawn by the Stroker. Will 
someone be kind enough to review these patches? The bug reports contain 
patches and images showing the differences in output.

Thanks,
Omair
