void rmInit (void)
An initialization routine, rmInit() will perform 4 steps:
1) initialize the internal scene graph datastructure
2) precompute trigonometric values used for primitive tessellation
3) initialize the internal font registry datastructure
4) output the OpenRM copyright notice
After these steps are performed, RM is not yet fully functional,
since a rendering context must be created, bound to an RMpipe, and
that context made current in order for rendering to proceed.

void rmFinish (void)
rmFinish() is used to cleanse the OpenRM component manager, and is
typically called as part of an application's shutdown procedure. It
will also delete the scene graph rooted at rmRootNode(), but will not
delete scene graph nodes that are not part of the directed acyclic
graph connected to rmRootNode().
