//  FILE: W3DOverlordAircraftDraw.h 
//  Author: Mark Lorenzen, April 2003
//  Desc: Units that recieve portable structure upgrades (like the OverlordTnk) have a super specific special need.
//  He needs his rider to draw explicitly after him,
//  and he needs direct access to get that rider when everyone else can't see it because of the OverlordContain.
//  In the case of aircraft (Helix, SpectreGunship, etc.) we need this draw module which mimics the OverlordTnkDraw
//  but does not draw treads, trackmarks, turrets, etc. Whee!
