-/** \file opencloseopen.c
- * Simple test for Mesa bug #508473. Create a window and rendering context.
- * Draw a single frame. Close the window, destroy the context, and close
- * the display. Re-open the display, create a new window and context. This
- * should work, but, at least as of Mesa 5.1, it segfaults. See the bug
- * report for more details.
- *
- * Most of the code here was lifed from various other Mesa xdemos.
