Use a base multiplier to keep the existing option range (1-15).
SDL2 >= 2.18 allows for considerably smoother scrolling, but
basic support for earlier versions is included.

Small viewport signs are drawn with FS_SMALL, so there is no need to duplicate text effect strings for both normal and small versions.
This also avoids an extra string format when text effect positions are updated.

If string parameters are not set correctly, FormatString can read out of bounds and crash the game.
This does not fix the root cause, just a nasty symptom.
When a NewGRF overrides another, any translation table that the overriding NewGRF installs will also be installed in the target file.
This allows the overridden NewGRF to make use of a cargo or rail/road type translation table without directly modifying the original file.
Sounds are loaded into memory on first use, using the SoundLoader interface to support format conversion. Sounds are retained in memory to avoid reloading every time a sound is played.
This deduplicates WAV header parsing between NewGRF and baseset sounds, and will allow different audio formats to be supported.

Allows quickly finding the EngineID given the type, grfid and local id of an engine, instead a linear scan.
This can reduce loading time when lots of engines are present and also affects performance in-game.
Lookup can be on the order of 10000 times faster.
The pointer was already captured and converted to a unqiue_ptr, but hidden within the call stack.
This now makes it clearer that the object passed to Add.*NewsItem will become owned by the news item.
Engines defined outside the original range did not have their cargo type/cargo label fields initialised properly.
If these engines are also not assigned a cargo type, they would therefore use the cargo in slot 0 instead of falling back to first refittable.
