-=============================== NOTES ==============================
-NOTE: Things starting with TODO are sometimes only suggestions.
-
-NOTE: iostream.imbue(std::locale("C")) is very slow
-NOTE: Global locale is now set at initialization
-
-NOTE: If VBO (EHM_STATIC) is used, remember to explicitly free the
-      hardware buffer (it is not freed automatically)
-
-NOTE: A random to-do list saved here as documentation:
-A list of "active blocks" in which stuff happens. (+=done)
-	+ Add a never-resetted game timer to the server
-	+ Add a timestamp value to blocks
-	+ The simple rule: All blocks near some player are "active"
-	- Do stuff in real time in active blocks
-		+ Handle objects
-		- Grow grass, delete leaves without a tree
-		- Spawn some mobs based on some rules
-		- Transform cobble to mossy cobble near water
-		- Run a custom script
-		- ...And all kinds of other dynamic stuff
-	+ Keep track of when a block becomes active and becomes inactive
-	+ When a block goes inactive:
-		+ Store objects statically to block
-		+ Store timer value as the timestamp
-	+ When a block goes active:
-		+ Create active objects out of static objects
-		- Simulate the results of what would have happened if it would have
-		  been active for all the time
-		  	- Grow a lot of grass and so on
-	+ Initially it is fine to send information about every active object
-	  to every player. Eventually it should be modified to only send info
-	  about the nearest ones.
-	  	+ This was left to be done by the old system and it sends only the
-		  nearest ones.

-	Enormous jungle + a surface dungeon at ~(250,0,0)
-
-Old, wild and random suggestions that probably won't be done:
--------------------------------------------------------------
-
-SUGG: If player is on ground, mainly fetch ground-level blocks
-
-SUGG: Expose Connection's seqnums and ACKs to server and client.
-      - This enables saving many packets and making a faster connection
-	  - This also enables server to check if client has received the
-	    most recent block sent, for example.
-SUGG: Add a sane bandwidth throttling system to Connection
-
-SUGG: More fine-grained control of client's dumping of blocks from
-      memory
-	  - ...What does this mean in the first place?
-
-SUGG: A map editing mode (similar to dedicated server mode)
-
-SUGG: Transfer more blocks in a single packet
-SUGG: A blockdata combiner class, to which blocks are added and at
-      destruction it sends all the stuff in as few packets as possible.
-SUGG: Make a PACKET_COMBINED which contains many subpackets. Utilize
-      it by sending more stuff in a single packet.
-	  - Add a packet queue to RemoteClient, from which packets will be
-	    combined with object data packets
-		- This is not exactly trivial: the object data packets are
-		  sometimes very big by themselves
-	  - This might not give much network performance gain though.
-
-SUGG: Precalculate lighting translation table at runtime (at startup)
-      - This is not doable because it is currently hand-made and not
-	    based on some mathematical function.
-		- Note: This has been changing lately
-
-SUGG: A version number to blocks, which increments when the block is
-      modified (node add/remove, water update, lighting update)
-	  - This can then be used to make sure the most recent version of
-	    a block has been sent to client, for example
-
-SUGG: Make the amount of blocks sending to client and the total
-	  amount of blocks dynamically limited. Transferring blocks is the
-	  main network eater of this system, so it is the one that has
-	  to be throttled so that RTTs stay low.
-
-SUGG: Meshes of blocks could be split into 6 meshes facing into
-      different directions and then only those drawn that need to be
-
-SUGG: Background music based on cellular automata?
-      http://www.earslap.com/projectslab/otomata
-
-SUGG: Simple light color information to air
-
-SUGG: Server-side objects could be moved based on nodes to enable very
-      lightweight operation and simple AI
-	- Not practical; client would still need to show smooth movement.
-
-SUGG: Make a system for pregenerating quick information for mapblocks, so
-	  that the client can show them as cubes before they are actually sent
-	  or even generated.
-
-SUGG: Erosion simulation at map generation time
-    - This might be plausible if larger areas of map were pregenerated
-	  without lighting (which is slow)
-	- Simulate water flows, which would carve out dirt fast and
-	  then turn stone into gravel and sand and relocate it.
-	- How about relocating minerals, too? Coal and gold in
-	  downstream sand and gravel would be kind of cool
-	  - This would need a better way of handling minerals, mainly
-		to have mineral content as a separate field. the first
-		parameter field is free for this.
-	- Simulate rock falling from cliffs when water has removed
-	  enough solid rock from the bottom
-
-SUGG: For non-mapgen FarMesh: Add a per-sector database to store surface
-      stuff as simple flags/values
-      - Light?
-	  - A building?
-	  And at some point make the server send this data to the client too,
-	  instead of referring to the noise functions
-	  - Ground height
-	  - Surface ground type
-	  - Trees?
-
-Gaming ideas:
--------------
-
-- Aim for something like controlling a single dwarf in Dwarf Fortress
-- The player could go faster by a crafting a boat, or riding an animal
-- Random NPC traders. what else?
-
-Game content:
--------------
-
-- When furnace is destroyed, move items to player's inventory
-- Add lots of stuff
-- Glass blocks
-- Growing grass, decaying leaves
-	- This can be done in the active blocks I guess.
-	- Lots of stuff can be done in the active blocks.
-	- Uh, is there an active block list somewhere? I think not. Add it.
-- Breaking weak structures
-	- This can probably be accomplished in the same way as grass
-- Player health points
-	- When player dies, throw items on map (needs better item-on-map
-	  implementation)
-- Cobble to get mossy if near water
-- More slots in furnace source list, so that multiple ingredients
-  are possible.
-- Keys to chests?
-
-- The Treasure Guard; a big monster with a hammer
-	- The hammer does great damage, shakes the ground and removes a block
-	- You can drop on top of it, and have some time to attack there
-	  before he shakes you off
-
-- Maybe the difficulty could come from monsters getting tougher in
-  far-away places, and the player starting to need something from
-  there when time goes by.
-  - The player would have some of that stuff at the beginning, and
-    would need new supplies of it when it runs out
-
-- A bomb
-- A spread-items-on-map routine for the bomb, and for dying players
-
-- Fighting:
-  - Proper sword swing simulation
-  - Player should get damage from colliding to a wall at high speed
-
-Documentation:
---------------
-
-Build system / running:
------------------------
-
-Networking and serialization:
------------------------------
-
-SUGG: Fix address to be ipv6 compatible
-
-User Interface:
----------------
-
-Graphics:
----------
-
-SUGG: Combine MapBlock's face caches to so big pieces that VBO
-      can be used
-      - That is >500 vertices
-	  - This is not easy; all the MapBlocks close to the player would
-	    still need to be drawn separately and combining the blocks
-		would have to happen in a background thread
-
-SUGG: Make fetching sector's blocks more efficient when rendering
-      sectors that have very large amounts of blocks (on client)
-	  - Is this necessary at all?
-
-SUGG: Draw cubes in inventory directly with 3D drawing commands, so that
-      animating them is easier.
-
-SUGG: Option for enabling proper alpha channel for textures
-
-TODO: Flowing water animation
-
-TODO: A setting for enabling bilinear filtering for textures
-
-TODO: Better control of draw_control.wanted_max_blocks
-
-TODO: Further investigate the use of GPU lighting in addition to the
-      current one
-
-TODO: Artificial (night) light could be more yellow colored than sunlight.
-      - This is technically doable.
-	  - Also the actual colors of the textures could be made less colorful
-	    in the dark but it's a bit more difficult.
-
-SUGG: Somehow make the night less colorful
-
-TODO: Occlusion culling
-      - At the same time, move some of the renderMap() block choosing code
-        to the same place as where the new culling happens.
-      - Shoot some rays per frame and when ready, make a new list of
-	    blocks for usage of renderMap and give it a new pointer to it.
-
-Configuration:
---------------
-
-Client:
--------
-
-TODO: Untie client network operations from framerate
-      - Needs some input queues or something
-	  - This won't give much performance boost because calculating block
-	    meshes takes so long
-
-SUGG: Make morning and evening transition more smooth and maybe shorter
-
-TODO: Don't update all meshes always on single node changes, but
-      check which ones should be updated
-	  - implement Map::updateNodeMeshes() and the usage of it
-	  - It will give almost always a 4x boost in mesh update performance.
-
-- A weapon engine
-
-- Tool/weapon visualization
-
-FIXME: When disconnected to the menu, memory is not freed properly
-
-TODO: Investigate how much the mesh generator thread gets used when
-      transferring map data
-
-Server:
--------
-
-SUGG: Make an option to the server to disable building and digging near
-      the starting position
-
-FIXME: Server sometimes goes into some infinite PeerNotFoundException loop
-
-* Fix the problem with the server constantly saving one or a few
-  blocks? List the first saved block, maybe it explains.
-  - It is probably caused by oscillating water
-  - TODO: Investigate if this still happens (this is a very old one)
-* Make a small history check to transformLiquids to detect and log
-  continuous oscillations, in such detail that they can be fixed.
-
-FIXME: The new optimized map sending doesn't sometimes send enough blocks
-       from big caves and such
-FIXME: Block send distance configuration does not take effect for some reason
-
-Environment:
-------------
-
-TODO: Add proper hooks to when adding and removing active blocks
-
-TODO: Finish the ActiveBlockModifier stuff and use it for something
-
-Objects:
---------
-
-TODO: Get rid of MapBlockObjects and use only ActiveObjects
-	- Skipping the MapBlockObject data is nasty - there is no "total
-	  length" stored; have to make a SkipMBOs function which contains
-	  enough of the current code to skip them properly.
-
-SUGG: MovingObject::move and Player::move are basically the same.
-      combine them.
-	- NOTE: This is a bit tricky because player has the sneaking ability
-	- NOTE: Player::move is more up-to-date.
-	- NOTE: There is a simple move implementation now in collision.{h,cpp}
-	- NOTE: MovingObject will be deleted (MapBlockObject)
-
-TODO: Add a long step function to objects that is called with the time
-      difference when block activates
-
-Map:
-----
-
-TODO: Flowing water to actually contain flow direction information
-      - There is a space for this - it just has to be implemented.
-
-TODO: Consider smoothening cave floors after generating them
-
-TODO: Fix make_tree, make_* to use seed-position-consistent pseudorandom
-	  - delta also
-
-Misc. stuff:
-------------
-TODO: Make sure server handles removing grass when a block is placed (etc)
-      - The client should not do it by itself
-	  - NOTE: I think nobody does it currently...
-TODO: Block cube placement around player's head
-TODO: Protocol version field
-TODO: Think about using same bits for material for fences and doors, for
-	  example
-
-SUGG: Restart irrlicht completely when coming back to main menu from game.
-	- This gets rid of everything that is stored in irrlicht's caches.
-	- This might be needed for texture pack selection in menu
-
-TODO: Merge bahamada's audio stuff (clean patch available)

-Texture Overrides
-=================
-
-You can override the textures of a node from a texture pack using
-texture overrides. To do this, create a file in a texture pack
-called override.txt
-
-Basic Format
-------------
-
-Each line in an override.txt file is a rule. It consists of
-
-	nodename face-selector texture
-
-For example,
-
-	default:dirt_with_grass sides default_stone.png
-
-You can use ^ operators as usual:
-
-	default:dirt_with_grass sides default_stone.png^[brighten
-
-Face Selectors
---------------
-
-| face-selector | behavior                                          |
-|---------------|---------------------------------------------------|
-| left          | x-                                                |

+Minetest Texture Pack Reference
+===============================
+
+Texture packs allow you to replace textures provided by a mod with your own
+textures.
+
+Texture pack directory structure
+--------------------------------
+
+    textures
+    |-- Texture Pack
+    |   |-- screenshot.png
+    |   |-- description.txt

+
+### Texture Pack
+This is a directory containing the entire contents of a single texture pack.
+It can be chosen more or less freely and will also become the name of the
+texture pack. The name must not be “base”.
+
+### `description.txt`
+A file containing a short description of the texture pack to be shown in the
+texture packs tab.
+
+### `screenshot.png`
+A preview image showing an in-game screenshot of this texture pack; it will be
+shown in the texture packs tab. It should have an aspect ratio of 3:2 and a
+minimum size of 300×200 pixels.
+
+### `your_texture_1.png`, `your_texture_2.png`, etc.
+Any other PNG files will be interpreted as textures. They must have the same
+names as the textures they are supposed to override. For example, to override
+the apple texture of Minetest Game, add a PNG file named `default_apple.png`.
+
+The custom textures do not necceessarily require the same size as their
+originals, but this might be required for a few particular textures. When
+unsure, just test your texture pack in-game.
+
+Texture modifiers
+-----------------
+
+See lua_api.txt for texture modifiers
+
+Special textures
+----------------
+
+These texture names are hardcoded into the engine but can also be overwritten
+by texture packs. All existing fallback textures can be found in the directory
+`textures/base/pack`.
+

+
+Texture Overrides
+-----------------
+
+You can override the textures of a node from a texture pack using
+texture overrides. To do this, create a file in a texture pack
+called override.txt
+
+Each line in an override.txt file is a rule. It consists of
+
+	nodename face-selector texture
+
+For example,
+
+	default:dirt_with_grass sides default_stone.png
+
+You can use ^ operators as usual:
+
+	default:dirt_with_grass sides default_stone.png^[brighten
+
+Here are face selectors you can choose from:
+
+| face-selector | behavior                                          |
+|---------------|---------------------------------------------------|
+| left          | x-                                                |
+| right         | x+                                                |
+| front         | z-                                                |
+| back          | z+                                                |
+| top           | y+                                                |
+| bottom        | y-                                                |
+| sides         | x-, x+, z-, z+                                    |
+| all           | All faces. You can also use '*' instead of 'all'. |

+- Added in version 27.
+- This contains 12 flags, each of them corresponds to a direction.
+- Indicates if the light is correct at the sides of a map block.
+  Lighting may not be correct if the light changed, but a neighbor
+  block was not loaded at that time.
+  If these flags are false, Minetest will automatically recompute light
+  when both this block and its required neighbor are loaded.
+- The bit order is:
+  nothing,  nothing,  nothing,  nothing,
+  night X-, night Y-, night Z-, night Z+, night Y+, night X+,
+  day X-,   day Y-,   day Z-,   day Z+,   day Y+,   day X+.
+  Where 'day' is for the day light bank, 'night' is for the night
+  light bank.
+  The 'nothing' bits should be always set, as they will be used
+  to indicate if direct sunlight spreading is finished.
+- Example: if the block at (0, 0, 0) has
+  lighting_complete = 0b1111111111111110,
+  then Minetest will correct lighting in the day light bank when
+  the block at (1, 0, 0) is also loaded.
