(svn r7757) -Fix (r7621): x64 did not compile because query_d was too big. Reorder the elements
a bit so it fits (alignment issues).

(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 r7635) -Fix (r7618, r7621): Guard against recursive deletion. It is possible that when a
parent window is deleted it deletes its child (always) and in turn, through some
code the child initiates the deletion of the parent which, if not guarded
against, deletes the child and so on...

(svn r7621) -Codechange: Rework ShowQuery into a general modal popup window. It gets passed
a parent pointer which will be blocked as long as the popup is open. This
applies to newgrf-apply, heightmap warning, genworld progress.

(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 r7523) -Feature: Add the possibility to change the newgrf configuration of a running game.
This is only possible in SP (or in the intro menu). During game play you will
get a confirmation window when applying the changes as some actions can crash
OpenTTD and/or make your current game unplayable.

(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 r7410) -Codechange/Fix: Remove useless and unfollowable programmatic-resize, and implement it
in a sane way. Correctly specify resize flags for windows and only manually change the
widgets that the resize system cannot handle (eg centering). This changes r6562, and
probably some other commits

(svn r7274) -Codechange [utf8]: Add input/output unicode support. This actually only changes win32
since it uses UTF16 for file access. To keep os-specific code to a minimum, OpenTTD
uses UTF8 internally everywhere, converting to OS-type when needed (save/load/screenshot/etc.)

(svn r7206) -Codechange: Remove (some of) the magic needed for windows that could be invalid after
a call to DeleteWindow() somewhere else. Also do some cleanup with AllowWindowDescFront()

(svn r7200) -Codechange: remove unneeded redraw (console.c), coding style, use FindWindowById
instead of _windows loop (viewport.c), remove dump-code (mixer.c), MSVC6 borkdness
in stdafx.h, constness (viewport.c), variable localization (win32.c), comments (window.c)

(svn r7195) -Feature: [FS#297, optional elrails] New patches/vehicles option 'disable electrified railways'.
(original patch by maedhros, ideas: peter1138, Darkvater, Rubidium, Patrick, Eddi|zuHause, ..)

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

(svn r7000) -Fix: Incorrect use of e->we.click when the event is a 'place'. This didn't cause any
bugs so far because the 'click' element was at the same position in the union for both
events.

(svn r6954) -Feature: Constrain the drawing of a string inside an editbox to the dimensions of
the widget it is in. This allows for typing longer text into an editbox (if maxwidth
allows of course) and scroll around properly.

(svn r6938) -Codechange: Comments, typo, variable naming, whitespace, strecpy and simplification
of order_gui (only disable a single widget if not local player, all others aren't
visible anyways).

(svn r6937) -Codechange: Add an InitializeTextBuffer() function that handles setting up the
textbuffer instead of typing it out each and every time.

(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 r6879) -Codechange: Remove the superflouos argument CharsetFilter parameter from HandleEditBoxKey
as the same information is present in querystr_d->afilter
-Also (&((querystr_d *)&WP(w, querystr_d))->text is the same as &WP(w, querystr_d).text

(svn r6821) -Codechange: For the measurement tool do not show the tooltip when the selection
is only a single tile. Seems this was a bit annoying to some ;)

(svn r6776) -Codechange: Use IsValidPlayer() function to determine of a PlayerID is an
actual playable player (< MAX_PLAYERS) or not.

(svn r6758) -Feature: Add a measurement tool that will show dimensions and height
differences of various draggable tools (inspiration, concept and double
checking by MeusH).

(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 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 r6462) -Codechange: Have GetStringWidth() return width as well as the height bounding
box of the string. Therefore rename the function to GetStringBoundingRect()
and have it return a BoundingRect type of width/height

(svn r6405) -Codechange: When showing tooltips, properly position the tooltip, considering
cursor size and cursor offset (hotspot). The maximum and minimum y-values
for the tooltip are just below the mainbar and statusbar. Also, if the tooltip
would be too low, flip it above the cursor.

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

(svn r5999) -Feature: change the original date format to a 32 bits format based at the year 0.
The game date subsystem now allows someone to start in the year 0 and continue
up to the year 5 000 000. However, you currently cannot build anything before
1920 as there is no newgrf support for dates before 1920 or after 2090 yet.

(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

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

(svn r5926) -Codechange: make _cur_year contain the full year, instead of the offset since 1920
-Codechange: store all year related variables that are _not_ stored in a savegame/transported over the network in the same format as _cur_year

(svn r5918) -Cleanup: rename ConvertDayToYMD/ConvertYMDToDay as they really convert a Date to/from a YearMonthDay.
-Cleanup: swap ConvertDateToYMD's parameters to make the order consistent with the name of the function.

(svn r5916) -Cleanup: use MIN_YEAR/MAX_YEAR for the year boundaries and BASE_YEAR when comparing _cur_year with a 'full' year.
-Cleanup: replace some magic '1920' values with BASE_YEAR.

(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 r5714) Backport from branches/TGP (r5701 and r5711)
-Fix: < > boxes in patch-settings didn't grey out when they hit the limit of their range
-Codechange: while at it, prettyfied DrawArrowButtons() a bit
-Fix: < > boxes in industry production window (when cheat enabled) had a minor glitch

(svn r4342) Change the first two parameters of commands - virtual pixel coordinates of the tile to operate on - to a TileIndex
Remove DoCommandByTile(), because now it does the same as DoCommand()

(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 r3713) - Fix up the cheats window a little. The cheats code is still abominable, but at least a bit more readable now.
Use the now generalized ReadValue/WriteValue functions as well as using general variable-types (SLE_VAR, instead of custom CE_ ones).
Remove the CE_CLICK type and use a SLE_BOOL type instead with a flag of CE_CLICK.
Remove stepsize from the struct. The stepsize is automatically calculated from the minimum and maximum values (in 20 steps).

(svn r3421) - Revert r3412 as it didn't work.
- Fix station builder issue by checking the tile is in bounds.

(svn r3247) - Fix: "[ 1335580 ] sticky windows not sticky anymore"
Determine clicked status of sticky icon from window flags rather than the widget click state. This keeps the status in one place where it can't get out of sync.

(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 r3173) Use the trinary operator and switch to improve readability
Also align short cases nicely

(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 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 r3001) s/Player*/const Player*/
s/byte/PlayerID/
s/int/PlayerID/
and related changes

(svn r2866) Move all functions and tables which aren't directly involved in managing the sprite heap to a new file gfxinit.c.
This doesn't ease the global variable mess, but makes the distinction between sprite heap and gfx loading routines easier.
