-0.6.2-RC2 (2008-07-25)
-------------------------------------------------------------------------
-- Fix: Building through the wrong side of a drive through station was allowed [FS#2166] (r13822)
-- Fix: Check for vehicle length changes outside a depot (callback 0x11) and give a warning about that [FS#2150] (r13816)
-- Fix: Several minor memory leaks. They only happened once per game (r13809, 13810)
-- Fix: Checking for train waiting at other side of two-way signal was broken [FS#2162] (r13806)
-- Fix: Some revision checking code was unintentionally disabled (r13776)
-- Fix: Enforce the validity of a NetworkAction (chat packet) issued by a client (r13775)
-- Fix: Selecting non-full length vehicles in the depot gui would place the "mouse pointer" out of the center of the vehicle making it hard to "aim" [FS#2147] (r13759)
-- Fix: NewGRF rail continuation would always mark a tunnel on the same axis as connected, even when the tunnel faces the wrong direction (r13734)
-- Fix: Assumption that non-north tiles of a house do not have the 1x1 building bit set was flawed with some NewGRFs. This caused the amount of houses to differ, which causes the town radii to differ, which causes desyncs when towns are expanded (r13729)
-- Fix: Possible desync on the autorenew settings 20+ game years (i.e. 4.5+ hours) after a company was started (r13718)
-- Fix: Any player could construct new companies [FS#2144] (r13716)
-- Fix: Remove the unique_id from the message that a client has joined as it is only exposes the unique_id more than needed (r13714)
-- Fix: Possible crash on creating a network packet (r13713)
-- Fix: Enforce the length restrictions of company and president name in the commands too (r13712)

-0.6.2-RC1 (2008-07-16)
-------------------------------------------------------------------------
-- Fix: Possible buffer overflow in string truncation code (r13700)
-- Fix: Handle SETX(Y) properly when truncating a string instead of ignoring it and returning a too long string (r13699)
-- Fix: In some cases the (sound) mixer could overflow causing artefacts in the sound [FS#2120] (r13695)
-- Fix: Do not rely on .tar files always ending with a block of zeros (r13693)
-- Fix: Make sure a command is ran in the context of autoreplace or not (r13691)
-- Fix: In the case that elrails and 'realistic' acceleration are disabled all electrified engines would have no power on load, until the vehicle got turned around, loaded or got into a depot [FS#2102]- Fix: Saving TTD imported games in recession failed due to wrong (and unneeded) type conversions in the saveload code [FS#2131] (r13679)
-- Fix: Inactive companies from old (TTD) saves could be marked active in some cases, which then loads garbage in their statistics and such [FS#2126] (r13676)
-- Fix: Memory leak when NewGRFs got forcefully disabled and they defined GOTO labels (r13675)
-- Fix: Crash when drawing a non-real sprite caused by NewGRF interference [FS#2127] (r13674)
-- Fix: Desync when building electrified trains on a dedicated server that was started with electrification disabled [FS#2122] (r13673)
-- Fix: Bus/truck forgetting go-to-depot order when entering a non-drivethrough road stop [FS#2117] (r13664)
-- Fix: Server crashing when banning the rconning client (r13661)
-- Fix: Signals were not updated correctly when a player removed a non-existing track piece (r13626)
-- Fix: Crash when one tries to raise the nothern corner of MP_VOID tiles (i.e. the southern corner of the tiles on the southern map edge) in the scenario editor [FS#2106] (r13624)
-- Fix: Only the front of a RV would be considered when determining to what cargos a vehicle can be refitted instead of all cargos [FS#2109] (r13622)
-- Fix: If the first bridge can not be build for a given length, then none of the other bridges can. Effectively meaning that if someone replaces the first bridge with a bridge that can be only 3 tiles longs then only other bridges that can be 3 tiles long will be buildable, but only if they are 3 tiles long [FS#2100] (r13611)
-- Fix: Signal states could be propagated through waypoints built in orthogonal axis (r13589)
-- Fix: [OSX] 10.5 failed to switch to fullscreen (r13584)
-- Fix: RVs continueing onto next DT station when they are build adjacent to them [FS#2040] (r13581)
-- Fix: Disable static NewGRFs when non-static NewGRFs query them in the context of network games. This makes it impossible for static NewGRFs to disable non-static NewGRFs and 'bad' things happening because the non-static NewGRF doesn't know about the static NewGRF (r13576)
-- Fix: Properly count number of non-north housetiles [FS#2083] (r13518)
-- Fix: Incorrect usage of strtoul (r13508)
-- Fix: Clear the memory for the new AI during the loading of a savegame so it does not try to execute commands generated in a different savegame, which could be resulting in the AI trying to give orders to stations that do not exist (r13505)
-- Fix: Drawing of zoomed out partial sprites could cause deadlocks or crashes (r13502)
-- Fix: First determine where to *exactly* build a house before asking a NewGRF whether the location is good instead of possibly moving the house a tile after the NewGRF said the location is good (r13489)
-- Fix: Track was not removed on company bankrupcy when there was a ship on lower halftile (r13488)
-- Fix: Let ships also navigate on half-tile sloped watery rail tiles (r13485)
-- Fix: Division by zero when one would press 'd' (skip order) when there's no order (r13409)
-- Fix: Do not crash when resolving vehicle sprite groups with zero sprites (r13397)
-- Fix: In the purchase list, CB36 for capacity was not called for the first part of rail and road vehicles (r13385)
-- Fix: Loading of very old OpenTTD savegames was broken (r13373)

-
-

-------------------------------------------------------------------------
-- Fix: Do not send rcon commands of the server to the first client but do directly execute those on the server (r13137)
-- Fix: For multiheaded engines, halve power and running cost when used instead of when loading, to allow callback values to work properly (r13074)

-- Fix: Update build industry window when raw_industry_construction setting is modified (r13060)
-- Fix: Revert changes to multihead engine weight -- the original values were correct (r13023)
-- Fix: Debugging was not possible with MSVC 2008 (r12996)
-- Fix: List used for sorting GRFs was not freed (r12993)
-- Fix: Default difficulty settings were different to TTD's original settings [FS#1977] (r12951)
-- Fix: All vehicles would be available when an original scenario would be played [FS#1982] (r12948)
-- Fix: Keep only first 15 bits for non failed callback results (r12947)
-- Fix: Reading/modifying invalid data under some circumstances (r12943)
-- Fix: Minor errors related to industries accepted/produced cargo (r12933)
-- Fix: Town rating was affected even after the test run (r12920)
-- Fix: Flood road tiles even when there are road works in progress [FS#1965] (r12919)
-- Fix: Do not initialize Station struct with tile=0, buoys will never change that value [FS#1960] (r12915)
-- Fix: Game crash when a spectator/server tried to show an engine with no owner when a NewGRF requested a specific variable (r12914)
-- Fix: Report reverse sprite status (FD/FE) to NewGRF for manually toggled vehicles (r12910)
-- Fix: Vehicles going twice to a depot when the automatic service interfered with the current order [FS#1985] (r12629)

-------------------------------------------------------------------------
-- Fix: Vehicle groups, engine replacement rules and player/company names were not properly reset/freed after bankrupt (r12906)
-- Fix: Remove trams from savegames saved in OTTD without tram support, it is better than to simply crash [FS#1953] (r12904)
-- Fix: GCC on FreeBSD does not support -dumpmachine causing configure to fail. Use g++ instead [FS#1928] (r12876)
-- Fix: Make the town rating tests use less memory and much quicker (r12859)
-- Fix: Usage of AutoPtr made (trying to) build stuff very (time) expensive (r12857, r12855)
-- Fix: Ensure that prop 25 is set for all vehicles in the consist before other properties as it could cause desyncs (r12856)
-- Fix: Too much catenary was drawn about tunnel entrances, middle bridge pieces and non-rail station tiles (r12853, r12852)
-- Fix: Use YAPF for fairly old savegames from before YAPF was introduced (r12845)
-- Fix: The industry tick trigger should only be triggered once every 256 ticks, not every tick... Also bail out of the triggers a little earlier if you know they are not going to happen anyway (r12844)
-- Fix: Inconsistent use of 8/15-bitness of NewGRF callback results with respect to TTDP's implementation of the specification (r12819, r12818, r12759)
-- Fix: Possible out of bounds array access (r12809)
-- Fix: Enforce autorenew values range in command (r12808)
-- Fix: Vehicles could break down during loading and keep loading. The intention of the break down code is not to break down when having zero speed, therefor break downs now do not happen when loading [FS#1938] (r12795)
-- Fix: [OSX] In some rare cases when using an uncalibrated monitor the system colour space could not be retrieved. Show an error when this happens instead of just trying an assertion (r12776)

-- Fix: Increase default sound buffer size only for Vista [FS#1914] (r12708)
-- Fix: Do not crash very hard on unrecognised savegames, just go back to the intro menu instead (r12707)
-- Fix: In some cases a news messages would not be shown [FS#1906] (r12683)
-- Fix: Removing road pieces from a town gave you twice the intended penalty [FS#1920] (r12682)
-- Fix: When a road vehicle has a tram only stop multiple times in a row in it's orders, only the first one would be skipped [FS#1918] (r12678)
-- Fix: Colour remaps on station sprites only worked for company colours [FS#1902] (r12674)
-- Fix: Remove buggy buoys at tile 0 from old TTDP savegames (r12642)
-- Fix: Possible NULL pointer dereference when reading some NewGRF data [FS#1913] (r12637)
-- Fix: Infinite loop in case your compiler decides that enums are unsigned by default (r12622)

-- Fix: Binding to a specific IP could cause OpenTTD to not register properly with the masterserver if one has multiple external interfaces (r12574)

-- Fix: Redraw the signal GUI when the signal drag density changes in the patch settings and vice versa (r12553)
-- Fix: Do not install scenarios into the current user's homedir when running 'make install', that is silly. Simply always install scenarios system wide instead (r12542)

-- Feature: Increase sprite limit from 16384 sprites to 16777216 sprites (r8128, r8129)
-- Feature: Add the ability to load savegames when you do not have the exact GRF files in your list. GRF files that are found based on GRF ID (but not on matching md5sum) are used instead of disabling them. This does not affect MP games, there you still need an exact match (r8106)

-- Codechange: Make opening a new toolbar not overlapping its parent one, by locating it under the parent, and aligned with the left side of it [FS#1310] (r11256)
-- Codechange: Do not brute force determine the first vehicle in the chain or previous vehicle, but do it by properly accounting the previous and first pointers when updating the next pointer. This gives a performance increase of about 15% when there are a lot of vehicles in the game (r11011)
-- Codechange: Cache expensive NewGRF station variables during sprite lookups/callbacks (r10509)
-- Codechange: Keep track of the origin, time of travel and accumulated feeder share (transfers) of individual pieces of cargo.

-- Codechange: Do not limit the cost of tunnels (r10248)

-- Fix: Do not create shores in canyons (r11438)
-- Fix: Starting OpenTTD with DOS files made it look weird out of the box (r11433)

-- Fix: Add missing elrail sprites for some rail build buttons/cursors (r11350)
-- Fix: Trees can now be planted on bare land without making it grassy, planting tree in desert does not make it grassy for the first tile-cycle and when a tree dies in desert, it no longer becomes a snowy tile for the first tile-cycle (r11244)
-- Fix: The explosion vehicles were placed too far to the south [FS#1312] (r11234)
-- Fix: One could sell vehicles that were crashed in a depot, which would still yield money/one could construct trains of crashed vehicles [FS#1307, FS#1228] (r11229, r11230)
-- Fix: Electric trains were not shown as stopped in depots when converting it from elrail -> normal rail [FS#1260] (r11167)
-- Fix: A lot of graphical glitches by changing some bounding boxes. It is not perfect yet, but a *very* good step into the right direction (r11128)
-- Fix: When autorenew is enabled and it cannot renew the vehicle anymore (because the player cannot build the engine), the ageing warnings as if autorenew is not enabled are shown [FS#553] (r11064)
-- Fix: Inconsistency between rail<->elrail conversions of different kinds of rail containing tiles (normal rail, stations, depots, etc) [FS#1182] (r11059)
-- Fix: Crash when having the Finance window opened of the player you are cheating to [FS#1177] (r11028)
-- Fix: Switching players (using the cheat) crashed on Big Endian machines [FS#1150] (r11023)

-- Fix: Do not display income/expenses when they do not belong to a "valid" tile, like the money cheat/giving money [FS#1175] (r11021)
-- Fix: One could not give money when (s)he had too much money or rather: when casting the amount of money to an int32 becomes negative [FS#1174] (r11020)
-- Fix: When determining the gender of a string, do not assume that the gender is in the front of the string when there can be case switching code at that location [FS#1104] (r10792)
-- Fix: Determining whether there is a tunnel going under the lowered area is only needed in two directions instead of all four, so take the directions (one for each axis) to the nearest border (along the given axis) [FS#1058] (r10686)
-- Fix: Graphical glitches when the "link landscape toolbar" patch is turned on when opening one of the construction toolbars [FS#1076] (r10685)
-- Fix: Trolly AI did not know about steep slopes, and used wrong tileh in some cases [FS#1070] (r10655)
-- Fix: Be consistent with the space between the company name and the player number, i.e. always put a space between them [FS#1052] (r10627)

-- Fix: Do not segfault when you quit in the end-of-the-game screen [FS#1020] (r10548)
-- Fix: When Cheat-Window is open and a new month happens, the window was not redrawn instantly (r10547)
-- Fix: You can now have both Available Train as Available Ship window open [FS#1026] (r10546)
-- Fix: Cargo payment rates overflow and cargo payment rates diverge from cost rates making it impossible to make any profit after a certain number of years. Both are solved by stopping the inflation after 170 years; there is absolutely no point in continuing the inflation after that as it only makes the game have overflows at some point that cannot be solved; using larger variables only delays the inevitable [FS#1028] (r10541)
-- Fix: Error dialog was sometimes shown on all clients when a command failed instead of only the client that actually did the command [FS#1015] (r10501)
-- Fix: The network protocol check for required NewGRFs sent static NewGRFs too (r10414)
-- Fix: When landscape generating, allow for 200ms between screen updates instead of updating every 200ms. Previously slow screen updates would result in very slow map generation (r10396)
-- Fix: One could only build a limited number of stations before one had to rename them [FS#278] (r10320)
-- Fix: Acceleration not calculated properly when a train goes up a hill between tunnels [FS#786] (r10317)
-- Fix: [YAPF] Now it is no longer needed to invalidate the YAPF segment cache every tick in MP (read performance increase). Segment cost now does not contain the curves between segments. As a result the cache should be now accurate (r10302)
-- Fix: [YAPF] Assertion triggered in some special cases [FS#901] (r10301)
-- Fix: Flush stdout on dedicated server output to ensure an update of stdout [FS#775] (r10295)
-- Fix: With smooth_economy, when industry production hit 32, it stayed there for ever. Give it some chance to get out of that uber-lowness (although it is a very slim chance, at least it has one) (r10290)
-- Fix: Also age engines that are not front-engines [FS#202] (r10288)
-- Fix: Money overflow bugs in many locations [FS#723] (r10212)

-- Fix: A vehicle without visual effects is not per definition unpowered (r9802)
-- Fix: Do not assume that trains running on monorail/maglev cannot smoke/spark (r9801)
-- Fix: Play sound effects based on the engine class, not the rail type (r9800)
-- Fix: Separate engine class and engine running cost class (r9799)
-- Fix: Clone vehicles will no longer refit for free (r9689)
-- Fix: Improved loading does not use a huge amount of processing power anymore when having a lot of trains [FS#423] (r9683)
-- Fix: Truncate the NewGRF information text in the NewGRF GUI if it is too long (r9449)
-- Fix: Cancel in password queries reduces amount of players in the network game when they have not joined the game yet [FS#688] r9378
-- Fix: If all news-setting buttons show 'full', make the ALL-button show 'full' too (r9137)
-- Fix: Open and close messages now have their own setting, so you can hide economy changes, but do show open/close of industries [FS#525] (r9097)
-- Fix: Do not make owner signs transparent, as then you loose the information who it owns [FS#637] (r9067)
-- Fix: Store the owner of a statue, so when it gets removed, the town is notified of it [FS#638] (r9066)
-- Fix: Inactive connections are not automatically kicked, i.e. people who only open a telnet (or similar) connection to a server [FS#115] (r9038)
-- Fix: Do not select a disabled platform length/number of track count when going out of drag-drop mode [FS#450] (r8999)
-- Fix: Make an aircraft at 400 km/h go as fast as a train at 400 km/h (r8973)
-- Fix: You were unable to build roads in the scenario editor when there is no town 0, even though there are other towns (r8608)
-- Fix: Road Vehicles now can obtain a slot even if the station is very spread out [FS#577] (r8536)
-- Fix: Allow lumber mill to cut trees only when they are full grown (r8535)
-- Fix: Segmentation fault when the toolbar gets removed and you have selected one of the items in a sub menu of the toolbar (r8533)
-- Fix: Remove phantom oil rigs sometimes present in old savegames (r8485)
-- Fix: When a station is removed, vehicles do not get excessive payment any longer, as the origin TILE is now stored as long as the origin STATION for the transported cargoes (r8144)
-- Fix: The game could crash when the chat key (<ENTER>) is pressed too vehemently during the join of the game. Your client's id does not exist in the clients list yet, and returns NULL (r8132)
-- Fix: Rail vehicles can no longer enter tunnels or bridgeheads with wrong railtype (r7976)
-- Fix: When path finding onto a bridge or tunnel end from previous tile (but not warping from the opposite end) check the enter direction. This fixes signal setting if a rail ends on the top of a tunnel end (r7718)
-- Fix: When following path for signals, do not skip back to the previous tile, as for tunnels and bridge ends the entering direction is wrong (r7717)
-- Fix: [YAPF] suppress 'Train is lost' message if path finding ended on the first two-way red signal due to YAPF.rail_firstred_twoway_eol option (r7628)
-- Fix: [OPF] signal update was incorrectly propagated (r7620)

-- Fix: Trains would not get flooded when they are at the lower part of a tile that would become a coast tile after flooding [FS#1127] (r10892)
-- Fix: Removing road with the road removal tool would also work with a negative bank account, making the bank account even more negative than it was [FS#1125] (r10890)

-- Fix: [Windows] Do not try to minimise or restore the window when closing OpenTTD [FS#998] (r10835)

-- Feature: console command to get the current game date (r10137)
-- Fix: Waypoints could be renamed when you are not the owner (r10368)
-- Fix: Smooth economy did not close primary industries and it allowed increasing of production of industries that should not have rising productions (r10348, r10347, r10290)
-- Fix: Acceleration for trains on slopes is not calculated properly [FS#786] (r10344, r10317)

-- Fix: Rail could be destroyed when building tunnels (r10306)
-- Fix: Flush the output of the dedicated server console (r10295)

-- Fix: Take the age of the front vehicle for station rating (r10246)
-- Fix: Terraforming wipes out canals. Now you always have to remove the canal before terraforming, instead of "just" removing the canal [FS#594] (r10240)
-- Fix: Only 2 trains could crash at one time as collision checking stopped on the first hit. This could technically cause desyncs in network games as the collision hash order is not guaranteed [FS#892] (r10222)
-- Fix: Land under foundations was terraform when it shouldn't be terraformed [FS#882, FS#890] (r10219)

-- Fix: SetCurrentGrfLangID returned the wrong language ids for most languages (r10130)
-- Fix: Some NewGRFs use the same (unused in the "current" climate) sprite IDs. Normally this gives some artefacts, but when one NewGRF expects it to be a sprite and another NewGRF overwrites it with a non-sprite nasty things happen (drawing a non-sprite crashes OTTD) [FS#838] (r10109)
-- Fix: Multiple subsequent "give money" actions could result in duplicate messages that money has been transfered when it only happened once, or tell you paid money when you did not [FS#834, FS#839] (r10087, r10085)

This resulted in unaccounted missing sprite cache memory, and was exacerbated because the original missing sprite was not cached, so it did it again and again and again. Slowdowns and boom (r10038)
-- Fix: One could build on (some) slopes when building on slopes was disabled [FS#823] (r10030)
-- Fix: When deleting the first engine of a train with multiple engines, only reopen the train window if the player had the original train window open. This fixes 'random' windows opening for multiple players of the same company (r10028)
-- Fix: When selling trains, if there were no wagons between multiheaded engines the rear part could be checked despite having already been deleted (10023)

-
-OpenTTD has 32bpp support. This means: OpenTTD still is 8bpp, but it has the
-posibility to override the graphics with 32bpp. This means that it isn't a
-replacement of grf or newgrf, but simply an addition. If you want to use 32bpp
-graphics of a newgrf, you do need the newgrf itself too (with 8bpp graphics).
-
-
-The Format
-----------
-
-32bpp images are stored in PNG. They should go in:
-  data/sprites/<grfname>/<SpriteID>.png
-
-For example, a grfname would be 'openttd' (without .grf, lowercase), and the
-SpriteID 3, to override the 3rd sprite in openttd.grf with a 32bpp version.
-
-The format of this PNG can be almost anything, but we advise to use RGBA
-format. Alpha-channel is fully supported.
-
-As the core of OpenTTD is 8bpp, and because you of course want company colours
-in your images, you will need to add a mask for every sprite that needs colour
-remapping. The name is simular as above, only you have to put a 'm' behind the
-SpriteID. This image should be a 8bpp palette image, where the palette is the
-OpenTTD palette. Upon load of the PNG, the mask is loaded too, and overrides
-the RGB (not the Alpha) of the original PNG image, and replacing it with a
-8bpp color remapped and converted to 32bpp.
-
-An other thing that OpenTTD needs in your png, is 2 tEXt chunks: x_offs and
-y_offs. This to define the x- and y-offset, of course. Use the tool we supply
-to add this information. Sadly enough most graphical editors trashes those
-chunks upon save, so you have to readd it every time you save your image.
-
-Your images should be the same as the grf, in size.

+This is a guide to compile strgen on gcc
+
+All this is done in the makefile, so it's only interesting for people, who wants to alter something themselves (translators)
+
+HOWTO compile lng files:
+
+First you get strgen compiled (look below/download nightly build/run makefile)
+
+strgen takes the argument of a txt file and translates it to a lng file and places that lng file in the same dir as the txt file.
+
+Example 1:
+if you are in the root of your working copy (svn code), you should type
+strgen/strgen lang/english.txt
+to compile englist.lng. It will be placed in the lang dir
+
+Example 2:
+you have strgen but not the source and you want to compile a txt file in the same dir. YOu should type
+./strgen english.txt
+and you will get english.lng in the same dir
+
+You can change english to whatever language you want
+
+Commands used by strgen
+
+-v --version
+strgen will tell what svn revision it is based on
+
+-t
+strgen will add <TODO> to the missing strings and use the english strings while compiling
+this will need english.txt to be present
+
+-w
+strgen will print any missing strings to standard error output(stderr)
+this will need english.txt to be present

+/** @file elrail.c
+ * This file deals with displaying wires and pylons for electric railways.
+ * <h2>Basics</h2>
+ *
+ * <h3>Tile Types</h3>
+ *
+ * We have two different types of tiles in the drawing code:
+ * Normal Railway Tiles (NRTs) which can have more than one track on it, and
+ * Special Railways tiles (SRTs) which have only one track (like crossings, depots
+ * stations, etc).
+ *
+ * <h3>Location Categories</h3>
+ *
+ * All tiles are categorized into three location groups (TLG):
+ * Group 0: Tiles with both an even X coordinate and an even Y coordinate
+ * Group 1: Tiles with an even X and an odd Y coordinate
+ * Group 2: Tiles with an odd X and an even Y coordinate
+ * Group 3: Tiles with both an odd X and Y coordnate.
+ *
+ * <h3>Pylon Points</h3>
+ * <h4>Control Points</h4>
+ * A Pylon Control Point (PCP) is a position where a wire (or rather two)
+ * is mounted onto a pylon.
+ * Each NRT does contain 4 PCPs which are bitmapped to a byte
+ * variable and are represented by the DiagDirection enum
+ *
+ * Each track ends on two PCPs and thus requires one pylon on each end. However,
+ * there is one exception: Straight-and-level tracks only have one pylon every
+ * other tile.
+ *
+ * Now on each edge there are two PCPs: One from each adjacent tile. Both PCPs
+ * are merged using an OR operation (i. e. if one tile needs a PCP at the postion
+ * in question, both tiles get it).

+ * that are impossible (because the pylon would be situated on the track) and
+ * some that are preferred (because the pylon would be rectangular to the track).
