signal drawing. Includes some basic cleanup of the drawing functions
|
|
When a special groundtype below the track is encountered in the tileloop, always return even if groundtype hasn't changed.

caused a game crash. This only manifested with some newstations loaded.
Thanks to Richk67 for finding this.

-Added a function to obtain the axis of a waypoint
-Moved the waypoint layout tables from the depot layout tables into an own one
-Use GetRailTileSubtype

function where it is used and use a better array arrangement for it
|

custom ground sprites used the index of the rail type as an offset. With the introduction of elrails this offset is incorrect, so instead there is now a lookup table within the RailTypeInfo struct to explicitly list the offset.

Remove DoCommandByTile(), because now it does the same as DoCommand()

terraformed.
Fixes a bug where you could terraform a tunnel (fixed by r3228, but reverted that one)
Fixes a bug introduced by r3228 which allowed steep rail tiles resulting in ... unwanted effects such as display artifacts.
That means the terraform feature should not work as intended; it also uses _valid_tileh_slopes to determine valid configurations instead of hand-brewn stuff.
TODO: _terraform_err_tile and similar TileIndices should have INVALID_TILE as "unused", not 0. (0 is a valid tile).
