33Overview
34
35    This is an SGI internal (e.g. not documented or intended to be used
36    directly by applications) extension used only to help support
37    emulation of IrisGL through OpenGL.
38
39IP Status
40
41    Unknown.
42
43Issues
44
45    Unlikely to be documented; this is ancient work supported only for
46    legacy applications.

116Revision History
117
118    Initial revision (October 5, 2000) - placeholder spec for the actual
119    IGLOO interface in use on IRIX gfx. The existing specs were merged
120    into a single interface and are both obsolete and AFAIK never
121    implemented.
