-=============================== 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.

-Vim conversion regexpes for moving to extended content type storage:
-%s/\(\.\|->\)d \([!=]=\)/\1getContent() \2/g
-%s/content_features(\([^.]*\)\.d)/content_features(\1)/g
-%s/\(\.\|->\)d = \([^;]*\);/\1setContent(\2);/g

-%s/\.d;/.getContent();/g
-%s/\(content_liquid\|content_flowing_liquid\|make_liquid_flowing\|content_pointable\)(\([^.]*\).d)/\1(\2.getContent())/g
-Other things to note:
-- node.d = node.param0 (only in raw serialization; use getContent() otherwise)
-- node.param = node.param1
-- node.dir = node.param2
-- content_walkable(node.d) etc should be changed to
-  content_features(node).walkable etc
-- Also check for lines that store the result of getContent to a 8-bit
-  variable and fix them (result of getContent() must be stored in
-  content_t, which is 16-bit)

-NOTE: Seeds in 1260:6c77e7dbfd29:
-5721858502589302589:
-       Spawns you on a small sand island with a surface dungeon
-2983455799928051958:
-       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: Mineral and ground material properties
-      - This way mineral ground toughness can be calculated with just
-           some formula, as well as tool strengths. Sounds too.
-         - There are TODOs in appropriate files: material.h, content_mapnode.h
-
-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
-TODO: Move mineral to param2, increment map serialization version, add
-      conversion
-
-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)
-
-TODO: Move content_features to mapnode_content_features.{h,cpp} or so
-
-TODO: Fix item use() stuff; dropping a stack of cooked rats and eating
-      it gives 3 hearts and consumes all the rats.
