Compacting 3 booleans into 3 bits could save memory allocation, however this data is inside a union which also contains a 4-byte integer. As such this gives the cost penalty of a bit-field without any benefit.
This to prevent compilation issues between runs with and without precompiled
headers. Also remove the headers from the rest of the code base as they are
not needed there anymore, although they do relatively little harm.
Previously it checked the position in non-driving direction to "guess" whether
a ground vehicle was using the function, so on tunnels/bridges it could either
return the Z of the (virtual) ground compared to the Z of the path the vehicle
would take.
When coming across any docking tile (for example, all tiles around
an oilrig are docking tiles), it always at least added a penalty
of 3 times a normal tile, even when there are no ships on them.
In result, the pathfinder got suggested to always go around docking
tiles. This was most likely not the intention of the change made in
31db4f8d5e.
YAPF could end up in a situation where it sets the best intermediate node
to a node whose construction is never finalized (i.e. it is never added to
the open list). The content of the node would be overwritten in the next
round, potentially sending the vehicle to an unwanted location.
YAPF was constantly measuring its performance, but only at
certain debug-levels this information was shown.
Now after years, I sincerely wonder if anyone still knows about this
feature and who still use it. Especially with the new framerate window,
this detailed performance is not as meaningful anymore as it once
was.
Basically, follow_track.hpp contains a fix for half-tiles, but
this wasn't duplicated for when trying to find a depot and in
a few other places. This makes sure all places act the same.
CMake works on all our supported platforms, like MSVC, Mingw, GCC,
Clang, and many more. It allows for a single way of doing things,
so no longer we need shell scripts and vbs scripts to work on all
our supported platforms.
Additionally, CMake allows to generate project files for like MSVC,
KDevelop, etc.
This heavily reduces the lines of code we need to support multiple
platforms from a project perspective.
Addtiionally, this heavily improves our detection of libraries, etc.
