[gradsusr] Grads 2.1.a3 - Problem plotting Intel graphic

[Graziano Giuliani]

On Archlinux xdemo.c works without any problems.

If I use directly output to X1I have the problem.
If I go through Xephir, display is ok.

Xephyr -br -ac -noreset -screen 800x600 :1 &
DISPLAY=:1 grads

This can help other users with new rendering stacks until permanent solution is 
found. Compositor problem? GL problem?
