Cut function now skips polygons that are completely inside the cutting area, instead of needlessly processing over them and not getting cut results
removed old point-on-polygon/findwall code

rewrote elevator queuing system
collision detection failure bug fixed
reworked pipe shafts and crawl spaces
new cinematic intro added (will be enhanced later)
new functionality added to the simulator control panel
automation added to the simulator control panel
new buildings added
building texture resolutions fixed
ModelViewer application added

Version 0.95b (build 144)

minor code changes
adapted for the new TrueVision3D 6.2 engine

Version 0.95 (build 140)

Changelog begins during 0.95 development.
