/* gfx Philosophy
|
|
|
|
The GFX system is a higher level abstraction that is independent of the
|
|
DD-DDGR interface. gfx uses the DD-DDGR interface, but not the other way
|
|
around. You may use GFX calls and DD-DDGR calls interchangably with older
|
|
functions. Any newer graphic functionality for Descent 2 will use
|
|
GFX calls
