JavaOGLBAT java2d.demos.Transforms.SelectTx comparison tests fails with latest 2D PIT build, 2005-04-13.mustang.pit.

The test will render the java2d.demos.Transforms.SelectTx test first in default (non-OGL mode), then in OGL mode and compare the difference between both renderings. Normally for this test case there's a 100% similarity between images. With the PIT build the test case is failing due to 8.91% comparison difference.

Visually the two renderings appear the same. The diff image shows the difference to be with the shade of the yellow within the rectangle that contains Duke image.

- Attaching the image renderings from default and OGL mode.
- The failure is not reproducible with last Mustang promoted build, 1.6.0-b32
- The failure has only been seen on WinXP, with Nvidia GEForce FX5200 running the very latest drivers, 71.89_win2kxp_english
- The test case passes on Solaris10 and RHAS30 platforms in OGL mode
- The failure appears to be an off-by-one pixel difference. The failure still occurs if the comparison allows for +/- 1, +/- 2, +/- 3 pixel differences.

Steps to reproduce
==================
1) Set JAVA_HOME environment variable to 2D PIT Build
2) Launch 2D_JavaOGLBAT suite
gnumake all (or) sh suite.sh

- The test suite will flag an error for the java2d.demos.Transforms.SelectTx test.
