Nice work, Andreas.

Some tips for the next release:
- delete all the backup files (the files with a tilde (~) in the extension).
- the DOF, CFG, DDP, DCU and JBF files can go as well.
- limit the size of the textures. One of the demos has a 769KB texture (512x512 24-bit) that could quite easily by reduced to 256x256 with little loss in quality, but a huge reduction in file size.
- Demos\Models\Quake3BSP is missing Unit1.pas
- Provide the Terrain demo as a separate downloadable ZIP. It is by far the largest single module in the distribution.
