the ES work by adding an ES functionality wrapper to the Mesa- OpenGL library on my system -- So OpenGL on my system now looks like GL + GLES. I did a sanity test on all of the GLES calls now in Chromium by building a test application that does drawing using each ES call. This now works through the chromium system. > ------------------------------------------------------- > This SF.Net email is sponsored by: YOU BE THE JUDGE.
