The Old Way was to write a static defineType method, and then call it
from VrmlNamespace::defineBuiltIns.

All that has been obsoleted by changes in the rearchitecture branch. The
New Way is to implement NodeClass, NodeType, and Node classes for your
node. Node implementations get added to an implementation repository in
VrmlScene::initNodeClassMap, and then added to the scene scope in
VrmlScene::initScope. VrmlScene::initNodeClassMap is a temporary
measure. Once the cohesion issues in the library have been resolved, a
proper component registry (and registration procedure) will be
instituted.
