Gaming ideas:
-------------
- How would some GTA-style ideas work?
- Cars? Stealing? Unlawful stuff and cops? Lots of guns?
- Aim for something like controlling a single dwarf in Dwarf Fortress.
- RPG style?
- Space racer style?

VoxelManipulator, which is faster)
FIXME: The new texture stuff is slow on wine
- Actually it is not too slow; updating excess amount of meshes
when making footprints is too slow. It has to be fixed.
- A basic grassy ground block takes 20-40ms
- A bit more complicated block can take 270ms
- On linux, a similar one doesn't take long at all (14ms)
- Is it a bad std::string implementation of MSVC?
- Can take up to 200ms? Is it when loading textures or always?
- Updating excess amount of meshes when making footprints is too
slow. It has to be fixed.
-> implement Map::updateNodeMeshes()
TODO: Optimize TileSpec to only contain a reference number that
is fast to compare, which refers to a cached string
