//
// This is a patch for the Inventor 2.0 Texture code, which can
// send bad display lists indices to OpenGL.  The results can be
// anything from nothing (OpenGL interprets the command as an empty
// display list), to random OpenGL calls being made (if the display
// list index already exists), to a core dump.
//
//
// To apply this patch, compile this file into a .o and then link
// the .o before -lInventor.  The linker may give a warning.
// This is normal and expected.
//
