Last change on this file since 18370 was 18370, checked in by kjdon, 15 years ago

committed code submitted by Amin Hedjazi for making the GLI right to left. I worked on this code on the rtl-gli branch, then merged the branch back to the trunk at revision 18368. The branch code was slightly different in a couple of places where it shouldn't have been. So don't use the branch code next time. Start a new branch.
