*
* 36 4/22/99 5:17p Matt
* Changed the and & or fields in the grCodes struct to cc_and & cc_or,
* since the former names didn't work with some compilers.
*
* 35 3/01/99 2:58p Dan
* Set lighting type before wireframe search, because sometimes it was set
* wrong & the search wouldn't work. (MattT on Dan's machine)
