(svn r5946) -Add: merged the TGP branch to mainline. TGP adds:
- New optional landscape generator (TerraGenesis Perlin) - Load heightmaps (either BMP or PNG) - Progress dialog while generating worlds (no longer a 'hanging' screen) - New dialogs for NewGame, Create Scenario and Play Heightmap - Easier to configure your landscape - More things to configure (tree-placer, ..) - Speedup of world generation - New console command 'restart': restart the map EXACTLY as it was when you first started it (needs a game made after or with this commit) - New console command 'getseed': get the seed of your map and share it with others (of course only works with generated maps) - Many new, world generation related, things - Many internal cleanups and rewrites Many tnx to those people who helped making this: Belugas, DaleStan, glx, KUDr, RichK67, Rubidium, and TrueLight (alfabetic) Many tnx to those who helped testing: Arnau, Bjarni, and tokai (alfabetic) And to all other people who helped testing and sending comments / bugs Stats: 673 lines changed, 3534 new lines, 79 new strings
