* GameGui.c: new function GameGuiCalculateNextAircraftTime(), which calculates remaining time for next aircraft on the list.
* GameStructures.h: new parameter NextAircraftTime for TYPE_PLAYER structures.
* Game.c: added call to new function GameGuiCalculateNextAircraftTime().
* Game.c: GameRenderLevel() renamed to GameRenderTerrain().
* Game.c: GameRenderTerrainPrecalculations() has been created to perform some calculations which are stored in tables to be then looked up by GameRenderTerrain(). This should save us some calculation time during rendering process.
* Camera.c: added new CameraApplyCoordinatesToCartesianPos() prototype.
* GameGui.c: AircraftDataGPoly4 RGB data is now only calculated on startup.
* Game.c: new prototypes GameGetParkingDirection() and GameGetRunwayDirection().
* Slight optimizations into GameRenderLevel().
* Added some comment headers into Gfx.c.
* Aircraft.c: aircraft direction is now set according to runway direction when aircraft is created.
* Game.c: TILE_PARKING_2 was not included on AcceptedTiles[].
* Game.c: GameAssignRunwaytoAircraft() was not looking up runway exit/entry points correctly.
* Aircraft now prevents collision against other aircraft if state == STATE_TAXIING.
* Game: new event handlers for new Aircraft collision prevention algorithm.
* Font: although not compulsory, _blend_effect_lum should be volatile.
* Other minor changes.
* (Bugfix): PltParser was casting remaining time to uint8_t instead of uint16_t.
* Reduced file buffer size to original value.
* GfxDrawButton(): L1/R1/L2/R2 text is now printed on top of Lx/Rx button.
* Other minor changes.
* Sine-like effect used for runways now moved to SystemCalculateSine().
* Bugfix: ptrPlayer->FlightDataPage is now decreased if there aren't enough active aircraft.
* On main menu, 2 players option is now disabled if pad 2 is disconnected.
* More work on FPS measurement (not working yet).
* Number of used SPU voices is now returned on SfxUploadSound().
* Added some more comments on Game.c.
* On GamePathToTile(), duplicate checks for existing tile have been replaced by calls to GameWaypointCheckExisting().
* Some performance optimizations on Game.c (removed unneeded "for" loops).
* Timer 2 is now handler (ISR still not working).
* SYSTEM.CNF: EVENT parameter increased to 7.
* Makefile now rebuilds needed targets on modified header files.
* Some more work on GameEmergencyMode().
* Initial work on PSX mouse auto detection.
* Prototypes for RCNT2 I_MASK bit handling.
* Files needed for Game are now only loaded once, except from LEVEL1.PLT.
* Added DevMenu to get debug info.
* ISR_LoadMenuVBlank() does not stop when accessing SIO.
* On fopen() and SERIAL_INTERFACE defined, "#" is prepended and "@" is appended to filename string.
* (Bugfix): on AircraftGetTileFromFlightDataIndex(), a buffer overrun was caused when asking for index = AIRCRAFT_INVALID_IDX.
* Added new parameters for some building types. Still some work pending.
* Removed obsolete, unused functions.
* Performance optimization: routines inside GameCalculations() were computating a big loop several times, so this has been modified so that loop is only performed once.
* Initial implementation for GameGetAircraftTilemap(). Still some work TODO.
* Timers with no repeat flag were being set to NULL, but this is not actually desired!
* Reenabled transparency for aircraft shadow.
* Deprecated NotificationRequest flags, and replaced by system timer handling.
* DrawEnv and DispEnv buffers are no longer swapped using DMA commands, but GPIO. This ensures stability under real hw. TODO: how to fix in 2-player mode?
* Provisionally removed semi-transparency for aircraft shadow sprite.
* Remove unneeded whitespace character on pointer variables (unary operators should not have any whitespaces).
* SelectedAircraft index now increases or decreases automatically on aircraft added/removed.
* Started writing Plt generation routines. Still a lot of work TODO.
* Aircraft should not be removed on State == STATE_APPROACH.
* Initial implementation for finished game.
* Added some comments on System.c.
* GameGuiPrepareNotificationString() deprecated.
* Solved issues with linked list overflow. A detection mechanism has also been added.
* New state STATE_ENTERING_RWY.
* GameGuiActiveAircraftList has been moved from GameGui to Game module.
* Active aircraft list for each player is now updated each time that a new flight either appears or disappears.
* Other minor fixes.
