TMDs hold the polygon data for models, GsDOBJ2 allow
these to be easily manipulated in software;
GsLinkObject4 links the two together.

GsLinkObject4 should be called _after_ the TMD has been put
into main memory, and its addresses mapped onto real addresses
using GsMapModellingData.

The execution time is negligable.
