(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 r7446) -Feature: Double the length of the cargo and rating indicators in the station list window,
thanks for the inspiration Rince. Workings of the small 1-pixel wide bar have changed a
little. Up till now it was pretty random, now it is only drawn for stations with minimal
amount of cargo (<=30) and 1-pixel height is 5 units.

(svn r7445) -Codechange (r4822): Properly draw the cargo colours in the station list and centre the
cargo abbreviations. The window at least looks a lot better this way.

(svn r7444) -Codechange: Use one (global) cargo-colours array for drawing cargo-colours. Change Food
colour to pink everywhere (fixes FS#303)

(svn r7428) -Codechange: Give a more explicit name to the enum STATIONLIST_WIDGET_CARGONONE.
It is not "No Cargo selected", but rather station with no cargo waiting, thus STATIONLIST_WIDGET_NOCARGOWAITING.
Hoping it is now clearer for everyone (mainly me...).
Will fix the behaviour next time.

(svn r7413) -Fix[FS#386,#412]: Station list window NONE button now behaves correctly.
-Fix: Clicking on SORT button (same window) does not reset everything anymore.
-Featurette: cargo, NONE and both ALL buttons are now shown fully down on pressed, as the text is deported by one pixel on y and y
Some widgets enum and code clean-up

(svn r7205) -Fix [FS#350, SF#1560913]: Window allocation and deletion messed with the actual window
structs inside their array, and possibly invalidating pointers higher up.
Meaning that any function called within an wndproc could cause unknown/invalid pointers
once control was returned to this function. Solved by the introduction of an extra
abstraction layer, an array of z-window positions that is only concerned with the
pointers.

(svn r7022) -Fix [FS#292]: Properly guard against viewing company-sensitive information from
invalid players (eg spectators) which could lead to crashes.

(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))

(svn r6631) -Codechange: Use accessors for click_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 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 r6562) -Codechange: merged the vehicle list window widget arrays
It made no sense to maintain 8 nearly identically arrays when a single one can do the job
Also made the two buttons always use half of the bottom width each, even when resizing

(svn r6381) -Cleanup: make the '/* */' comments that span multiple lines more uniform.
-Cleanup: whitespace alignment of a few tables.

(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 r5887) -Cleanup: move date related functions, defines and variables to date.[ch]
-Cleanup: fix whitespace related coding style issues in date.[ch]
-Cleanup: make original comments doxygen compatible and remove/change outdated comments

(svn r4823) -Fix: Improved tooltips for sortable station lists.
-Credit: Chrishuebsch for initial idea and implementation of station filters

(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 r3073) int/byte -> EngineID/PlayerID/VehicleID

(svn r2594) Fix: [strgen] Misc updates to the string system.
- Renamed the plural command to "P" instead of "PLURAL". Now write something like this to append an s on plural: {P "" s}. (You can optionally still add an argument index to explicitly specifiy which number that's used)
- Removed the pluralized cargo strings from the string files. The new method is to use the plural specifier {P}
- Added support for genders. First add "##gender der das die" on top, then use {G=der} on a cargoname/industry to set the gender, and to switch between genders do something like {G neu neu neue} {STRING}
- Updated the swedish/english translation with P strings.

(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 r1845) - Revert r1835 since it totally screws network compiling
- Fix: fix some VS.NET warnings
- Add missing file to VS.NET project file

(svn r1770) -Fix: Hopefully last pieces of code that are containing a station-id
(and should be an uint16, not uint8)

(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 r1288) -Codechange: changed _map2 to an uint16. It is still saved and loaded as
an uint8 till the savegame version is bumped to version 5. Then it works
automaticly as a fully uint16. So _stations[] can not be increased till
after the bump!!

(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 r1009) -Feature: per-station vehicle lists
This adds a little button per vehicle class to the station window which opens a list of all vehicles that have this station on their schedule.
As side effect this gets rid of some global variables.

(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 r244) -Fix: Stations were not sorted for non-player-0 players
-Fix: Correctly resorting vehicle list of player when the list of another player is open.

(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 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
