(svn r7637) -Codechange: Change ShowQueryString to use a window pointer as a parent. If the
query has no parent (eg give money, rename waypoint), the global function
HandleOnEditText is used.

(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 r6926) -Codechange: Rename WWT_4 to WWT_TEXTBTN_2 and WWT_6 to WWT_INSET (credits to peter1138
for the aptly found name)
-Codechange: Remove the explicit numbering from WindowWidgetTypes

(svn r6925) -Codechange: Be more strict with widget distinctions. WWT_PANEL is only plain panel,
WWT_IMGBTN must contain an image for drawing. Renamed WWT_PANEL_2 to WWT_IMGBTN_2
because that is what it is. Added WWT_PUSHBTN that is either just a pushable button,
or a textbutton, which text's drawn dynamically independent of widget.

(svn r6884) -Codechange: Add strict bounds checking in string formatting system.
The last parameter should point to the end of the buffer (eg lastof(buf))
Courtesy of Tron.

(svn r6774) -Codechange: Rename the badly named OWNER_SPECTATOR to PLAYER_SPECTATOR and
put it into player.h where it belongs (instead of map.h)

(svn r6619) -Codechange: Use accessors for disabled_state.
Another step toward merging XTDwidget.
The only two files not converted (window.h and widget.c) will be done at the very last commit)

(svn r6169) -Codechange: Use GetString() instead of GetStringWithArgs() which should be
integral to strings.c

(svn r6055) -Codechange: added GetXXXArraySize, which returns HighestID + 1 (or, will do that).
It isn't the best name, but we couldn't find any better.
This unifies the pool-system even more.

(svn r6047) -Codechange: FOR_ALL now _only_ loops valid items, and skips invalid ones
-Codechange: use IsValidXXX where ever possible
Note: both changes to prepare for new pool system, which needs those changes.
For every pool there are 2 ugly lines, which will be removed when done
implementing new pool system.
Based on FS#13 by blathijs, partly implemented.

(svn r5944) -Merge TGP (r5578, r5579, r5724, r5726): -Feature: filter for textboxes to only
allow certain patterns (like numbers only)

(svn r3181) -Bracing
-Indentation
-Whitespace
-DeMorgan's Law
-Test with NULL or 0 for non-booleans
-'\0' instead of 0 for chars
-Remove redundantly redundant comments (like DoFoo(); // Do foo)
-Join multiple short lines with a single statement
-Split single lines with multiple statements
-Avoid assignments in if

(svn r3078) Some more stuff, which piled up:
- const, whitespace, indentation, bracing, GB/SB, pointless casts
- use the trinary operator where appropriate
- data types (uint[] -> AcceptedCargo, ...)
- if cascade -> switch
- if (ptr) -> if (ptr != NULL)
- DeMorgan's Law
- Fix some comments
- 0 -> '\0', change magic numbers to symbolic constants

(svn r3077) static, const, bracing, indentation, 0 -> '\0'/NULL, typos in comments, excess empty lines, minor other changes
nothing spectacular, just some stuff, which piled up

(svn r2702) -Codechange: Cleaned up the sprite code and replaced many magic numbers
by enums. There remains work in gfx.c to move the "transparency" and
"recolor" bits around to make space for more sprites. However, 2800
additional sprites can now be loaded. There also remains cleanup and
Doxygen work on many of the header files.

(svn r2580) Change: Added {INDUSTRY} command for printing industry names instead of the old {TOWN} {STRING} way.
- The formatting of the industry name can be controlled with the string STR_INDUSTRY_FORMAT.
Change: Changed several occurences of {STRING1} into {TOWN} to get rid of townnametype being used directly.

(svn r2572) - Codechange: [string] Changed string system so it's not as dependent on decode_parameters
- Feature: [strgen] Allow changing the order of parameters in translated strings.
- Use {1:TOWN} syntax to set the order.
- Codechange: [strgen] Rewrote lots of strgen internals.

(svn r2307) - Fix (regression): it was not possible to change the drive-side in the intro-game.
- CodeChange: remove unused "CANT_DO_THIS" double-string.

(svn r2297) - CodeChange: server-check the next batch of commands.
- CodeChange: since only the server will be able to modify difficulty settings, leave the checking of correct values besides, and trust users will join legit servers.
- CodeChange: for renaming signs, only check if GetDParam(); eg _decode_parameters is empty ('\0') or not, instead of the extra check of players, etc. That basically does the same thing. Also dirty sign two times when renaming, once before, once after the action. Because if the name becomes shorter and you update only after, garbage remains on the screen.
- CodeChange: made GetMaskOfTownActions() available to the town-cmd to double-check if the action was available to the player. For this purpose the hardcoded _local_player has been removed from the function and is now passed as a parameter.

(svn r1764) -Add: dynamic towns, you can now have up to 64k towns (let me know when
you have that amount of towns in a map ;))

(svn r1407) -Codechange: changed a lot around _stations, _vehicles, _towns and _industries
(in prepare of dynamic arrays):
- DEREF_XXX is changed into GetXXX
- All direct call are directed via GetXXX
- struct Industry has now an index-field
- ENUM'd some stuff
- Replaced home built loops with FOR_ALL_XXX
- Added _stations_size, _vehicles_size, ... which gives the length of the
array (which will be dynamic in the near future)
- Changed lengtof(XXX) to _XXX_size (e.g. _stations_size)
- Removed all endof(XXX) (because mostly it was part of a FOR_ALL_XXX)
- Made the sort-functions of all 4 dynamic
- Made all 4 Initialize functions more of the same
- Some minor tab-fixing and stuff
(tnx to Tron for proof-reading my 100kb patch ;))

Note for all: please do NOT directly call _stations, _vehicles, _towns and
_industries, but use the right wrapper to access them. Thank you.
Ps: please also do not use 'v++', where v is of type Vehicle *.

(svn r1348) -Feature: resizable windows. Read the comment in window.h to find out
how the system works. All useful windows are already made resizable. Enjoy :)
-Fix: fixed some GUI-glitches and flaws along the way

(svn r1214) -Feature: Stickified Industries (list & window), Smallmaps (all three), Stations (list & window) and Towns (list & window). I hope I didn't forget to update a widget somewhere :O
-Feature: With the sticky windows on and some unfortunate resizing of your game it the 'close' button might go outside of the playing field, making it impossible to close. Added an option to the Options menu that closes all windows, even if they are stickified ("Close ALL windows")

(svn r1179) Fix: Tooltips for vehicle list sorting
This has gotta be the greatest kick for Moriarty!

(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 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 r177) -Fix: padded out Widget code to solve warnings on C99 compiler (Tron)
-Fix: added WIDGETS_END macro for WWT_LAST which does this for all last widget-types

(svn r175) -Fix: [1023771] inconsistent/missing stations in station list. Forgot to change owner-sort after changing function.
-Codechange: some more asserts to vehicle-sorts to quickly find any possible problems.

(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.

(svn r122) Change: exclusive transport rights are now stored per town instead of per station
Exclusive rights from old savegames will be reset.

(svn r70) -Fix: typo in english.txt
-Add some debug messages for misc=1

(svn r66) -Fix Station list updated on station deletion/station rename
-Changed debug messages to comply with DEBUG(name, level) heuristics

(svn r3) -[1005611] Player Window patch: When looking in dropdownlist for player stuff, it will say
for all human players (Player #), not only for the first 2

(svn r2) -Fix [993829] UDP Fixes (lucaspiller)
-Fix change 255/0xFF to OWNER_SPECTATOR for
spectator stuff (TrueLight)
