register their 2D noises with multi_map globally and retrieve
them during map generation. multi_map takes care of reusing last
cached map in case the same layer is used for performance/ memory
reasons. In addition, it prepares an array of parameters so that
the noises can be used in any layer (truly availble globally) with
seeds different for each layer (but based on the seed passed
during registration via random seeding). Placeholder for global
3D maps added, but not implemented yet.
sort of cached table as per duane's underworlds mod. Introduced
shorthand alias mm for multi_map in case not other mods named mm
exist, so that it can be more easily used to reference the API, e.g.
to do vm_data[vi] = mm.node["default:cobble"] instead of having to
fully spell out multi_map
a fallback (or default if need be) generator in case no layer specified
generator is found. Added sample/ basis mod to demonstrate registration
of map generators. Rewrote Proxima Testauri map generator to conform to
multi_map, simple map generator is fallback in demo. Testauri now uses
a single noise which increases generation time but reduces memory usage.
To try and reduce generation time, it keeps track of the last layer used
and based on that will not reinitialize unless the layer changes.
