 The module is not active by default, and must be installed by calling
 _tnl_Wakeup().  This function installs internal tnl functions into all
 the vtxfmt dispatch hooks, thus taking over the task of transformation
 and lighting entirely:

 The module itself offers a minimal driver interface:

 Normally this is set to _tnl_RunPipeline(), however the driver can use
 this hook to wrap checks or other code around this call.
