(svn r7565) -Codechange: Rework DEBUG functionality. Look for appropiate debugging levels to
use in debug.h. grfmsg() is now used as a specific debug-function for grf.

(svn r7449) -Codechange: Rename _path to _paths as it is technically more correct, but mainly because
it interferes with OS/2 symbol in libc (psmedley)

(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

(svn r5764) - Cleanup: - Cleanup: Move the now unified FiosAlloc, compare_FiosItems, FiosFreeSavegameList, FiosMakeSavegameName, FiosDelete and FileExists to newly created file fios.c where it belongs.
- Fix: forgot to remove GetLanguageList from functions.h in previous commit

(svn r4105) - Feature: Add proper ISO-8859-15 <> LOCALCODE conversion. As the mess that is makefile can't properly support it at the moment, it is only available for MACOSX. Windows doesn't need FS conversion and I have no idea about OS/2 so it's disabled for them.
- CodeChange: Change the function GetCurrentLocale(). It returns the locale from some default environment-variables, plus a custom one defined as parameter. If all fail, it tries $LANG.

(svn r4019) -Fix: [OSX] stopped using iconv for 10.2.8, since it was added in 10.3
this have the sideeffect that 10.2.8 will still have the "failure to save with certain chars in the filename bug", but at least it can compile again

(svn r3966) -Fix: [OSX and some linux] [ 1157244 ] Can't save game if name contains german umlauts
now it saves correctly, but the load window still display some chars wrong (fix by ln-)

(svn r3281) -Feature: [OSX] added native cocoa sound and video drivers (egladil)
you can still use SDL drivers if you like and you have to run "make upgradeconf" to start using the cocoa drivers (or manually write WITH_COCOA:=1)
since SDL breaks the cocoa drivers, you can't compile with both SDL and cocoa support
Using cocoa drivers makes it easier to make universal binaries and it solves:
-FS#18 [OSX] SDL is weird in universal binaries
-FS#2 [OSX] lazy pointer crash on exit
-FS#10 [OSX] linking error when linking statically to SDL 1.2.8 (needless to explain this, but it means it should be able to compile statically with the default settings now)
-[ 1215073 ] Switching to large size out of fullscreen crashes
Using SDL drivers will still have those issues though

(svn r3096) - Feature: 'HOME' icon to saveload dialogs that jumps to the default save/load directory based on the dialog (added icon to openttd.grf, introduced FIOS_TYPE_DIRECT that allows arbitrary directory jumping).
- Fix: on Win32 capitalize the drive-letter in the saveload dialog windows when it is first opened.

(svn r2882) Some fixes for MorphOS (by tokai)
- Don't track dependencies on system headers
- Add an include path
- Silence a warning regarding a bad signal prototype
- Remove executable flag from pictures
- Add proper OTTD icon

(svn r2860) Fix some issues in the savegame/scenario list code:
-Fix: Sort the directories when making a scenario list
-Fix: Sort the directories when making a savegame list on Windows
-Fix: On OS/2 show the trailing \ if the current directory is a root directory
-Regression: On OS/2 the savegame list showed the scenario directory or crashed (probably introduced in r2609)
The rest is diff reduction between the 3 variants

(svn r2807) Fix two major bugs in the threaded save code:
- Do not dereference a local variable which no longer exists; this lead to random crashes when saving
- (Win32) Do not close a handle before it is used last
There are still many major problems (race conditions and resulting memory corruption/crashes) left

(svn r2728) -Fix/Feature: Change the driver probing algorithm
Instead of trying to start a single driver and bailing out if that fails, try to initialise one by one and use the first one which succeeds.
This should fix problems on machines with no sound card, where -s null had to be specified manually.

(svn r2703) - Feature: [OSX] Added a native alert window to show whatever error() needs to print (Tobin made this, while I fixed some issued in it)
- As a bonus, we now have an objective C file (os/macosx/macos.m) to use the functions Apple made to interact with OS stuff

(svn r2685) -Codechange: Split the music/sound/video drivers into separate files and move them into subfolders.
This results in shorter and hopefully easier to maintain files.
Note: I had to change paths in #include statements of some unrelated files, because I added the ottd base directory to the include path (-I.)

(svn r2583) Move OS specific code out of misc.c
Added support for Mersenne Twister random number generator (not implemented in network yet)
Wrap player randoms around #ifdef

(svn r2391) - Feature: saving games happen in a seperate thread so you no longer will have to wait such a long time (especially handy on bigger maps and multiplayer games). The mouse also changes into the 'ZZZ' state :P. The thread on windows is currently given a little-bit-less-than-normal priority so it should not interfere that much with the gameplay; it will take a bit longer though. Upon the exit of the game any pending saves are waited upon.
- Fix: fixed GetSavegameFormat() so that it takes the best compressor (highest), or a forced one added with the parameter
- Open issues:
1. Don't attempt to load a game while saving is in progress, it will kick you back to the intro-screen with only the vast ocean to look at.
2. The server is disabled from threaded-saving, but might be enabled in the future.
3. Current implementation only allows 1 additional running thread.
4. Stupid global variables.....grrr
Big thanks for TrueLight and the amazing memorypool :D

(svn r2101) statvfs() is availible on POSIX.1 conformant systems.
Also use a different field, which has a better chance of containing meaningful information, of the returned struct to determine the free space on the filesystem and fix a small bug introduced in r2100 (s/!=/==/)

(svn r1986) - Fix: free _config_file when shutting down openttd. Strange that Valgrind didn't catch this, kudos to TrueLight
- Feature (small): new command-line option -c <config_file>. You can have OpenTTD load alternative config files with this setup, handy for servers, or for saves from other players if you don't want to rename your own config. This will have to do until all game-related settings are saved ingame. Couldn't find the SF patch, so credits to the guy that wrote it.

(svn r1894) - Codechange: cleaned up the console a bit, wholly unified handling of text with that of editboxes
- Codechange: Introduction of Textbuf struct which not only holds physical data as length but also pixel-constrains (width) and information about the caret
- Codechange: Move Clipboard function to OS specific file. Currently only Windows has clipboard actions
- Feature: Editboxes, console and exit screen also accept the numeric-enter as a yes
- Feature: Navigation through text with cursor keys is possible, as well as arbitrary insertion (also paste) and deletion; both backspace and del keys. Functions DeleteTextBufferChar, InsertTextBufferChar and InsertTextBufferClipboard handle input and deletion. Navigation is done through MoveTextBufferPos.
- Fix: OTTD crash when opening 'add server' editbox
- CodeChange: fix up some stringwidth calculations in gfx.c. You can get the width in pixels of a character by calling GetCharacterWidth().

(svn r1479) -Added highscore chart (accessible from the difficulty window) with top5 companies for a given difficulty (select the difficulty in the menu)
-Added endgame score on 1 jan 2051 where you are added to the highscore if sufficiently large points have been accumulated. Game is paused while
-These values are saved in hs.dat; added read/write functions for it
-Added code to delete all windows to show charts. There is one issue left: somehow a news-gui pops up in front of the the chart at the end of the game.

(svn r1236) MorphOS: added make release like in OSX (tokai)
MorphOS: cleaned up the code telling the difference between AmigaOS and MorphOS (tokai)

(svn r970) Added 2nd data path for all non-windows OSes
added completely customizable lang path (all non-Windows OSes)

(svn r901) Small step in the process to clean up the DPARAM mess:
- reduce to 2 sizes (*DParam64 for 64bit values, *DParam for the rest)
- use inline functions instead of macros
- add assert()s to check for buffer overruns

(svn r869) Mac: finally made asserts open the console, so people should be able to see what went wrong even if they opened the game in the GUI
deleted the wrongly moved bemidi.cpp

(svn r815) Include strings.h only in the files which need it.
This should reduce the compile time after altering english.txt by about 1/3, because "only" 62 instead of 90 .c files must be recompiled.

(svn r607) -Patch: [ 985102 ] static cleanup
Thanks to lvoge

(svn r223) -Fix: Const correctness and miscellaneous fixes. Thank you Tron for your diligent fixing of warnings (and some possibly bugs) (Tron)
-CodeLayout: Remove trailing spaces and Windows linebreaks

(svn r207) -Codechange: randomizer handling
-Fix: desync problem fixes
-Fix: server doesnt hang anymore when a client timed out
-Feature: low latency connection enhancements [*net_sync_freq, *net_ready_ahead]

(svn r165) -Feature: Option to sort vehicles in vehicle-list window by different criteria. Total independent sort for all types and players. Periodic resort of list every 10 TTD days. Thank you for your graphical inspiration follow and buxo (since none of you provided any code).
-Fix: Sorter icon pointing down 'v' sorts in every window lowest value first, '^' highest value first
-CodeChange: move Dropdownlist from settings_gui.c to widget.c. More in place there.
