don't crash on bsp w/o vis don't crash with origin in the void (includes inside of structural brush)(do reset) grab point to analyse from camera position with nothing selected; grab from any objects selection too fix rendering issues read surfaces written by q3map2 correctly + faster rendering code print number of loaded drawsurfaces to console for evaluation of optimization done fix a couple of of leaks and crashes after new/delete
