e/Fahrenheit graphics API

Information
has gloss	eng: Fahrenheit was an effort to create a unified high-level API for 3D computer graphics to unify Direct3D and OpenGL. It was designed primarily by Microsoft and SGI and also included work from an HP-MS joint effort. Much of the original Fahrenheit project was abandoned, and Microsoft and SGI eventually gave up on attempts to work together. In the end only the scene graph portion of the Fahrenheit system was released, known as XSG, which disappeared shortly after release.
