(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 r7130) -Codechange: Handle the positioning of windows through the desc->left/top settings with
some special values (WDP_) instead of checking window-class. This also fixes FS#172
now that we can position windows arbitrarily and are not restricted to window-classes.

(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 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 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 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 r6406) -Codechange: Rename TileOffsByDir to TileOffsByDiagDir because it accepts
DiagDirections, and add TileOffsByDir that handles Directions.
-Codechange: Make the treeloop use TileOffsByDir().

(svn r4449) - NewStations, remove parameter to use first custom station when building a railway station. The parameters will be
changing.

(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 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 r3167) - NewGRF: Start moving custom station code to separate files.
Rewrite handling of station classes.
Allow for more than 8 station tile layouts.
Start of code to unload custom stations.

(svn r2798) -Codechange: Unified the rail toolbars into one that is modified by
request using the RailtypeInfo struct

(svn r2286) - CodeChange: paramcheck the next batch of commands.
- Fix (regression): fix up terraform land where every player can terraform land (towns, map generation), and player can terraform different corners; used for building tunnels

(svn r2285) - Codechange: Fix up some of the missing things from server-checking; namely bridge-type, bridge-length, dragged end-tile (bridge/station), station_spread
- Fix: [ 1197256 ] max station spread patch < 7 does not work. Station spread was not taking into account when not using drag&drop. Fix this up, and add a callback to the settings window to immediately reflect the changes.

(svn r2136) - Fix: [ 1174313 ] terrain hotkeys nonfunctional in scenario editor (D,Q,W,E,R,T,Y,U fltr)
- Fix: 'L' no longer opens ingame terraform bar in scenario editor bar, but the land generator one
- Feature: [ 1095110 ] Create Lake and draggable Create Desert tools (initial implementation GoneWacko), also added sticky buttons to land generator and town generator
- CodeChange: moved around some of the draggable tools, demystifying them
- CodeChange: change CmdBuildCanal to allow for XANDY dragging not only X or Y (only scenario editor)
- CodeChange: add some more enums to sprites.
- TODO: merge most of the ingame and scenario editor land terraform code. This can only be done after OnClickButton function is changed so it also includes the backreference to the widget being clicked, postponed to after 0.4.0

(svn r2046) -Codechange: moved all waypoint code to waypoint.c/waypoint.h
-Codechange: rewrote some functions while moving waypoint-stuff
-Add: added support for 64k waypoints
-Fix: made the waypoint struct a bit more logic (no bit-fucking)

(svn r1575) -Fix: Forgot to exit the construction phase for the waypoint window (if
you have newgrfs loaded)

(svn r1573) -Fix: Station and depot building mode is now terminated if the
corresponding windows are closed [ 1104277 ]

(svn r1571) Feature: Visually enhanced autorail placing
When using the autorail tool, the rail pieces which are going to be build are highlighted.
If a piece is shown in red, this indicates that the slope/rail combination is impossible. It does not tell you if the rail line construction might not be possible because of other obstacles, e.g. houses or water.

(svn r1386) Move TileIndexDiff to map.h
Move _tileoffs_by_dir to map.[ch] and encapsulate it in TileOffsByDir()

(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 r1254) - Fix: [ 993500 ] High bridge rendering error
- Changed button to open landscaping toolbar

(svn r1030) Some toolbar icons are arranged differently:
- Landscaping buttons have to be accessed from the landscaping toolbar
- Landscaping toolbar can be opened from all other toolbars
- The order of buttons in the docks toolbar now matches the other toolbars
- Landscaping toolbar has new keyboard shortcuts

(svn r925) Use sound enums
Also play the correct sound when a toyland road vehicle breaks down
