Xaero's World Map

+ Added a new option that lets you toggle texture compression, which is now OFF by default. I think it only makes sense to use texture compression on a very old machine or if you want to keep a larger map loaded at once.
* Singleplayer maps now load directly from the world save instead of files generated by the mod. This means that chunks generated before installing the mod will now be automatically discovered by the mod. Make sure your world is optimized (select your world -> Edit -> Optimize World) or it will take a very long time to load from the world save.
* Reworked map lighting to use multitexturing. This results in quicker map loading and more precise lighting. Lighting will "break" for old cache but it'll be automatically fixed and resaved. The loading speed improvement will only be noticeable afterwards. This change also reduces the per-region VRAM usage by about 70%.
* Fixed the map writer to use the full render distance.
* Fixed a bug in the map change detection which could cause map textures to not update sometimes. This happened mostly on superflat worlds.
* Fixed map size limiter unnecessarily removing some regions when you load new regions very fast.
* Improved handling of terrain slopes at the top of map textures.
* Fixed compatibility with BetterPortals mod.
* Fixed biome ids being unnecessarily saved sometimes.
* Fixed ladders being displayed as a black square in vanilla colours mode. Requires rediscovering the chunks to take effect on multiplayer. This also affects which blocks are ignored when writing/discovering the map in both colour modes.
* Fixed incorrect color byte order on big-endian machines.
* Other smaller bug fixes and optimizations.
