-=============================== NOTES ==============================\r
-NOTE: Things starting with TODO are sometimes only suggestions.\r
-\r
-NOTE: VBO cannot be turned on for fast-changing stuff because there\r
-      is an apparanet memory leak in irrlicht when using it (not sure)\r
-         - It is not a memory leak but some kind of a buffer.\r
-\r
-NOTE: iostream.imbue(std::locale("C")) is very slow\r
-NOTE: Global locale is now set at initialization\r
-\r
-Random suggeestions:\r
---------------------\r
-\r
-SUGG: Fix address to be ipv6 compatible\r
-\r
-NOTE: When a new sector is generated, it may change the ground level\r
-      of it's and it's neighbors border that two blocks that are\r
-         above and below each other and that are generated before and\r
-         after the sector heightmap generation (order doesn't matter),\r
-         can have a small gap between each other at the border.\r
-SUGG: Use same technique for sector heightmaps as what we're\r
-      using for UnlimitedHeightmap? (getting all neighbors\r
-         when generating)\r
-\r
-SUGG: Transfer more blocks in a single packet\r
-SUGG: A blockdata combiner class, to which blocks are added and at\r
-      destruction it sends all the stuff in as few packets as possible.\r
-\r
-SUGG: If player is on ground, mainly fetch ground-level blocks\r
-SUGG: Fetch stuff mainly from the viewing direction\r
-\r
-SUGG: Expose Connection's seqnums and ACKs to server and client.\r
-      - This enables saving many packets and making a faster connection\r
-         - This also enables server to check if client has received the\r
-           most recent block sent, for example.\r
-SUGG: Add a sane bandwidth throttling system to Connection\r
-\r
-SUGG: More fine-grained control of client's dumping of blocks from\r
-      memory\r
-         - ...What does this mean in the first place?\r
-\r
-SUGG: A map editing mode (similar to dedicated server mode)\r
-\r
-SUGG: Add a time value to the param of footstepped grass and check it\r
-      against a global timer when a block is accessed, to make old\r
-         steps fade away.\r
-\r
-SUGG: Make a copy of close-range environment on client for showing\r
-      on screen, with minimal mutexes to slow down the main loop\r
-\r
-SUGG: Make a PACKET_COMBINED which contains many subpackets. Utilize\r
-      it by sending more stuff in a single packet.\r
-         - Add a packet queue to RemoteClient, from which packets will be\r
-           combined with object data packets\r
-               - This is not exactly trivial: the object data packets are\r
-                 sometimes very big by themselves\r
-\r
-SUGG: Split MapBlockObject serialization to to-client and to-disk\r
-      - This will allow saving ages of rats on disk but not sending\r
-           them to clients\r
-\r
-SUGG: MovingObject::move and Player::move are basically the same.\r
-      combine them.\r
-         - NOTE: Player::move is more up-to-date.\r
-\r
-SUGG: Precalculate lighting translation table at runtime (at startup)\r
-      - This is not doable because it is currently hand-made and not\r
-           based on some mathematical function.\r
-               - Note: This has been changing lately\r
-\r
-SUGG: A version number to blocks, which increments when the block is\r
-      modified (node add/remove, water update, lighting update)\r
-         - This can then be used to make sure the most recent version of\r
-           a block has been sent to client\r
-\r
-SUGG: Make the amount of blocks sending to client and the total\r
-         amount of blocks dynamically limited. Transferring blocks is the\r
-         main network eater of this system, so it is the one that has\r
-         to be throttled so that RTTs stay low.\r
-\r
-SUGG: Meshes of blocks could be split into 6 meshes facing into\r
-      different directions and then only those drawn that need to be\r
-\r
-SUGG: Calculate lighting per vertex to get a lighting effect like in\r
-      bartwe's game\r
-\r
-Gaming ideas:\r
--------------\r
-\r
-- Aim for something like controlling a single dwarf in Dwarf Fortress\r
-\r
-- The player could go faster by a crafting a boat, or riding an animal\r
-\r
-- Random NPC traders. what else?\r

-TODO: Get rid of GotSplitPacketException\r
-\r
-GUI:\r
-----\r
-\r
-TODO: Add gui option to remove map\r
-\r
-TODO: Configuration menu, at least for keys\r
-\r
-Graphics:\r
----------\r
-\r
-TODO: Optimize day/night mesh updating somehow\r
-      - create copies of all textures for all lighting values and only\r
-           change texture for material?\r
-         - Umm... the collecting of the faces is the slow part\r
-           -> what about just changing the color values of the existing\r
-                  meshbuffers? It should go quite fast.\r
-                  - This is not easy; There'd need to be a buffer somewhere\r
-                    that would contain the night and day lighting values.\r
-                        - Actually if FastFaces would be stored, they could\r
-                          hold both values\r
-\r
-FEATURE: Combine MapBlock's face caches to so big pieces that VBO\r
-      gets used\r
-      - That is >500 vertices\r
-         - This is not easy; all the MapBlocks close to the player would\r
-           still need to be drawn separately and combining the blocks\r
-               would have to happen in a background thread\r
-\r
-TODO: Make fetching sector's blocks more efficient when rendering\r
-      sectors that have very large amounts of blocks (on client)\r
-         - Is this necessary at all?\r
-\r
-TODO: Flowing water animation\r
-\r
-* Combine meshes to bigger ones in ClientMap and set them EHM_STATIC\r
-\r
-SUGG: Draw cubes in inventory directly with 3D drawing commands, so that\r
-      animating them is easier.\r
-\r
-Configuration:\r
---------------\r
-\r
-Client:\r
--------\r
-\r
-TODO: Untie client network operations from framerate\r
-      - Needs some input queues or something\r
-\r
-SUGG: Make morning and evening transition more smooth and maybe shorter\r
-\r
-SUGG: Don't update all meshes always on single node changes, but\r
-      check which ones should be updated\r
-         - implement Map::updateNodeMeshes()\r
-\r
-TODO: Remove IrrlichtWrapper\r
-\r
-Server:\r
--------\r
-\r
-TODO: When player dies, throw items on map\r
-\r
-SUGG: Make an option to the server to disable building and digging near\r
-      the starting position\r
-\r
-TODO: Copy the text of the last picked sign to inventory in creative\r
-      mode\r
-\r
-TODO: Check what goes wrong with caching map to disk (Kray)\r
-      - Nothing?\r
-\r
-FIXME: Server sometimes goes into some infinite PeerNotFoundException loop\r
-\r
-* Fix the problem with the server constantly saving one or a few\r
-  blocks? List the first saved block, maybe it explains.\r
-  - It is probably caused by oscillating water\r
-* Make a small history check to transformLiquids to detect and log\r
-  continuous oscillations, in such detail that they can be fixed.\r
-\r
-Objects:\r
---------\r
-\r
-TODO: There has to be some better way to handle static objects than to\r
-      send them all the time. This affects signs and item objects.\r
-SUGG: Signs could be done in the same way as torches. For this, blocks\r
-      need an additional metadata field for the texts\r
-         - This is also needed for item container chests\r
-\r
-Block object server side:\r
-      - A "near blocks" buffer, in which some nearby blocks are stored.\r
-         - For all blocks in the buffer, objects are stepped(). This\r
-           means they are active.\r
-         - TODO: A global active buffer is needed for the server\r
-         - TODO: A timestamp to blocks\r
-      - TODO: All blocks going in and out of the buffer are recorded.\r
-           - TODO: For outgoing blocks, timestamp is written.\r
-           - TODO: For incoming blocks, time difference is calculated and\r
-             objects are stepped according to it.\r
-\r
-- When an active object goes far from a player, either delete\r
-  it or store it statically.\r
-- When a statically stored active object comes near a player,\r
-  recreate the active object\r
-\r
-* Continue making the scripting system:\r
-  * Make updateNodeMesh for a less verbose mesh update on add/removenode\r
-  * Switch to using a safe way for the self and env pointers\r
-  * Make some global environment hooks, like node placed and general\r
-    on_step()\r
-* Add a global Lua spawn handler and such\r
-* Get rid of MapBlockObjects\r
-* Other players could be sent to clients as LuaCAOs\r
-\r
-Map:\r
-----\r
-\r
-TODO: Mineral and ground material properties\r
-      - This way mineral ground toughness can be calculated with just\r
-           some formula, as well as tool strengths\r
-\r
-TODO: Flowing water to actually contain flow direction information\r
-\r
-FEATURE: Create a system that allows a huge amount of different "map\r
-            generator modules/filters"\r
-\r
-FEATURE: Erosion simulation at map generation time\r
-               - Simulate water flows, which would carve out dirt fast and\r
-                 then turn stone into gravel and sand and relocate it.\r
-               - How about relocating minerals, too? Coal and gold in\r
-                 downstream sand and gravel would be kind of cool\r
-                 - This would need a better way of handling minerals, mainly\r
-                   to have mineral content as a separate field. the first\r
-                       parameter field is free for this.\r
-               - Simulate rock falling from cliffs when water has removed\r
-                 enough solid rock from the bottom\r
-\r
-Mapgen v2 (not doing):\r
-* only_from_disk might not work anymore - check and fix it.\r
-* Make the generator to run in background and not blocking block\r
-  placement and transfer\r
-* Add some kind of erosion and other stuff that now is possible\r
-* Make client to fetch stuff asynchronously\r
-  - Needs method SyncProcessData\r
-* Better water generation (spread it to underwater caverns but don't\r
-  fill dungeons that don't touch big water masses)\r
-* When generating a chunk and the neighboring chunk doesn't have mud\r
-  and stuff yet and the ground is fairly flat, the mud will flow to\r
-  the other chunk making nasty straight walls when the other chunk\r
-  is generated. Fix it.\r
-\r
-Mapgen v4 (not doing):\r
-* only_from_disk might not work anymore - check and fix it.\r
-* Make the generator to run in background and not blocking block\r
-  placement and transfer\r
-* Make chunks to be tiled vertically too\r
-* MAKE IT FASTER\r
-\r
-Mapgen v3 (not doing):\r
-* Generate trees better\r
-  - Add a "trees_added" flag to sector, or something\r
-* How 'bout making turbulence controlled so that for a given 2d position\r
-  it can be completely turned off, and is usually so. This way generation\r
-  can be sped up a lot.\r
-* Add a way to generate a block partly, so that trees are not added, like\r
-  the chunks in v2\r
-* Add mud "discretely", not by guessing from the noise\r
-\r
-Mapgen v4:\r
-* This will be the final way.\r
-* Generate blocks in the same way as chunks, by copying a VoxelManipulator\r
-  from the map that is one block larger in all directions.\r
-\r
-Misc. stuff:\r
-------------\r
-* Make an "environment metafile" to store at least time of day\r
-* Move digging property stuff from material.{h,cpp} to mapnode.cpp...\r
-  - Or maybe move content_features to material.{h,cpp}?\r
-* Maybe:\r
-  Make a system for pregenerating quick information for mapblocks, so\r
-  that the client can show them as cubes before they are actually sent\r
-  or even generated.\r
-* Optimize VoxelManipulator lighting implementation by using indices\r
-  in place of coordinates?\r
-\r
-Making it more portable:\r
-------------------------\r
-* Some MSVC: std::sto* are defined without a namespace and collide\r
-  with the ones in utility.h\r
