[x3d-public] Finding more than one use of a DEF in VRML

[GPU Group]

double defining:
- this stymied me too, until I realized the DEF/USE are just for the
parser, and its the sequence that counts although different for different
browsers.
- if you redef 3 times, then USE, what will you get?
- that depends on the web3d browser, with some sticking to the first DEF,
some the last DEF.
