(svn r9040) -Codechange: the build window and CmdBuildAircraft() now shares the code to figure out if an aircraft is buildable in the hangar in question
This should help ensuring that the build command and the list are consistent in what aircraft are buildable

(svn r8946) -Feature: [NewGRF] Add support for vehicle variables 0xFE and 0xFF bit 10,
which is set when a vehicle was built during the exclusive testing phase.

(svn r8921) -Fix (FS#654): several issues related to removing all orders from an aircraft and removing the airport it was heading:
- the aircraft would go to (0, 0) and circle there. Clicking the 'eye' to jump to the aircraft in the main window could cause a segmentation fault.
- when rebuilding an airport with the StationID of the old airport could crash as the FTA state of the aircraft is higher than the number of states of the new airport, causing a crash of all clients and the server when assertions are enabled.
- when rebuilding an airport with the StationID of the old airport can bring the aircraft in a state where is keeps circling the airport.
To solve these issues all aircraft without a valid order will try to go to the nearest hangar it can safely get to (large jets do not land on small airports). If there is no hangar to go to, the airplane crashes (out of fuel).

(svn r8897) -Fix

Change the signature of GetNewVehiclePos():
-void GetNewVehiclePos(const Vehicle *v, GetNewVehiclePosResult *gp);
+GetNewVehiclePosResult GetNewVehiclePos(const Vehicle *v);

(svn r8835) -Fix

Remove dead code

(svn r8834) -Fix

Do not pass something to a function it better could figure out by itself

(svn r8822) -Fix

Variable scope, const

(svn r8763) -Fix

Don't do bogus initialisations and prefer simpler code

(svn r8755) -Fix

Abbreviate GetAirport(st->airport_type) to st->Airport()

(svn r8748) -Fix

-Codechange: Do not hardcode the airports with a short airstrip anymore, but make it a flag in AirportFTAClass

(svn r8747) -Fix

-Codechange: Make the encoding of accepted aircraft types of airports a bit more sensible and move the enum into struct AirportFTAClass

(svn r8743) -Fix

-Codechange: Add a Z adjustment attribute for helicopter pads to AirportFTAClass to get rid of some special cases for oilrigs and heliports

(svn r8661) -Fix: [depot windows] Enlarge the blocks in the depot window if a sprite is too big to fit (ships and aircraft only)
-Codechange: depot windows default now makes a 1x1 matrix and resize the window by block size*number of blocks
This will make less vehicle type specific code and easier to read resizing based on sprite sizes

(svn r8618) -Fix

Remove redundant assignments. The function call just before already does it

(svn r8617) -Fix

Fix harmless typo: s/,/;/

(svn r8610) -Codechange/Feature: rewrote the list handling in the autoreplace window
-The user will notice the following changes:
All vehicle types behaves in the same way
Adding/removing an engine (new design and so on) can no longer result in the window selecting a new engine
All valid replacements will be displayed since it looks at refitting options as well (this solves the missing ships with the newships GRF)
Since you can't replace an engine into itself, the engine selected in the left list will no longer appear in the right list

-The code changes:
Instead of looping all engines all the time, each list generates a list like the build windows
This ensures consistent list generation since only one function can loop all engines
Unified code for all vehicle types
It now use the lists to call the drawing code in the build vehicle window
Works on selected EngineIDs instead of selected index in the list

(svn r8559) -Fix

-Codechange: Put the airport movement data into struct AirportFTAClass

(svn r8550) -Fix

Building a vehicle does not involve allocating orders, so do not check whether orders could be allocated

(svn r8549) -Fix

Do not check whether the end of the depot array has been reached when building an aircraft. This cannot happen, just assert it really does not happen

(svn r8548) -Fix

Remove redundant second retrieval of the AircraftVehicleInfo when building an aircraft

(svn r8547) -Fix

Remove redundant second retrieval of the station and airport when building an aircraft

(svn r8498) -Fix

-Codechange: Move the update of the oil rig airport type to the recently (r8485) added loop

(svn r8430) -Fix

Replace the rather obscure control flow for handling aircraft/ship/train orders by something remotly comprehensible (see r3584)

(svn r8305) -Codechange: defining 'static const' in a header is a bit weird.
Above that, wince-gcc gave "unused variable" on every file which included airport.h... pretty annoying ;)

(svn r8128) -Codechange: Split sprite and palette remap into separate 32 bit values.
This lets us increase the sprite width from 14 to up to 29 bits,
effectively nulling the old sprite limit. Table changes in next commit.
