/*
* SGI Rendering Resource Manager API (?).
*
* written by Miguel de Icaza (miguel@nuclecu.unam.mx)
*
* Ok, even if SGI choosed to do mmap trough ioctls, their
* kernel support for virtualizing the graphics card is nice.
*
* We should be able to make graphic applications on Linux
* fly.
*
* This header file should be included from GNU libc as well.
