Method RebuildCachedData

trinity/Eve/Turret/EveTurretSet.cpp:1035–1104

-------------------------------------------------------------------------------- Description: This gets called when the geometry data has finished loading, so we have a whole lot of init's to do: - take the original vertex declaration, extend by one member for the 2nd stream, and create a new one - grab bounding sphere from mesh - analyze the skeleton: find the system bones and remember their indi
