I didn't apply the changes to a few macro-heavy files as Visual Studio removes all indentation from macros, whereas the indentation can be handy to see nesting.
Hopefully this pickVoxel function will fulfil most most need with
raycasting which aren't covered by the existing raycast functions.
It's essentially a wrapper around the current functions, using a custom
functor to store the position of a solid voxel as well as the previous
empty voxel. It doesn't require the user to provide a functor of their own,
just the value that they've assigned to empty voxels.
As well as the function itself, we also have a unit test as well as it
being built in the bindings.
