Writing vectors as strings is very common and should belong to `vector.*`. `minetest.pos_to_string` is also too long to write, implies that one should only use it for positions and leaves no spaces after the commas.
In compiler design especially, leaving behavior as "undefined" is a _strong_ condition that basically states that all possible integrity is violated; it's the kind of thing that happens when, say, dereferencing a pointer with unknown provenance, and most typically leads to a crash, but can result in all sorts of spectacular errors--thus, "it is undefined" how your program will melt down.
The pure-Lua implementation of `key_value_swap` does not permit UB _per se_ (assuming the implementation of Lua itself is sound), but does deterministically choose the value to which a key is mapped (the last in visitation order wins--since visitation order is arbitrary, _some_ value _will_ be chosen). Most importantly, the program won't do something wildly unexpected.

Add more detailed light detection functions, a function to get the artificial light (torches) and a function to get the sunlight as seen by the player (you can specify timeofday).

Features:
* Define Minimap available modes (surface/radar, scale) from Lua, using player:set_minimap_modes()
* New HUD elements for displaying minimap with custom size and placing
* New minimap mode for displaying a texture instead of the map
Fixes some other third person camera specific attachments.
Implements a single new flag for entities to be forced visible in first person mode.
Old mods do not need to be updated to use the new flag and are fully backwards compatible.
Allows catching a chatcommand call just after the command and the
parameters are parsed but before its existence is checked and before the
corresponding function is run. Returning `true` from a callback function
will prevent default handling of the command leaving mods to handle the
command manually.
"Predicts" whether something will be swapped for allow callbacks, then calls callbacks a second time with swapped properties.

* added vector.rotate
* added vector.forward_from_rotation and vector.up_from_rotation
* added vector.forward_up_to_rotatiton
* fixed some bugs and formatting with vector functions
* shortened name of some new vector functions and added documentation
* made vector.rotate not require a unit vector as axis
* fixed crash with vector.forward_up_to_rot
* renamed new vector functions, made vector.rotate apply a rotation matrix, old vector.rotate is now called vector.rotate_around_axis
* documented vector function changes
* removed some whitespace to appease luacheck
* implemented and fixed optimization of vector.rotate_around_axis by SmallJoker
* added some unit tests for rotation vector functions
* clarified that rotation vectors are in radians and according to the left hand rule
* hopefully appeased luacheck
* renamed rotation_to_horizontal to forward_at_rotation, rotation_to_vertical to up_at_rotation
* handled cases where sin or cos are 0 in rotation vector functions
* added more comments
* clarified documentation of rotation vector functions
* added more unit tests
* changed way in which vector.rotate_around_axis is adjusted for left handed coordinate systems
* made vector.rotate_around_axis actually left handed
* unrolled matrix multiplication

* removed documentation of removed vector functions
* clarified documentation and fixed styling of rotation vector functions
* restyled comments minorly
* spelling fixes and some hopefully better comments
* allowed 'up' to be missing from vector.directions_to_rotation and removed requirement for unit vectors as arguments
* made vector.rotate_around_axis() right handed again for consistency
* documented previous changes
* made matrix multiplication actually multiply

automatic_rotate does not make sense if it is absolute. Make it relative.
To avoid bouncing, set_rotation did not update the client when automatic_rotate was set. That's no longer necessary because the new spinning method applies the rotation on top of the current one, and the updates are necessary for set_rotation to actually transform the object.

This adds support for optional “off state” icons for statbars. “off state icons” can be used to denote the lack of something, like missing hearts or bubbles.
Add "off state" textures to the builtin statbars.
