* SGI Rendering Resource Manager API (?).

|
|
* 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.
