whenever we change to another renderer etc. and define it for the game and editor. The purpose of the function is to clean up references to Polymer resources like lights. This fixes 1) all lights becoming spot lights in the game and 2) an issue with maphack lights in the editor (can't recall which exactly). git-svn-id: https://svn.eduke32.com/eduke32@2006 1a8010ca-5511-0410-912e-c29ae57300e0
