Miscellaneous Improvement

Release 0.5.8

Restructure

• Enable free-slip neighbour logic on heightmap generation. SuperTerrain+ will generate neighbour biomemap before generating the central heightmap, so free-slip biomemap can be passed to heightmap generator for biome interpolation.
• Overhaul the structure of checkChunk() in STPChunkProvider for better nested neighbour logic.
• Split STPFreeSlipManager into three different files, being STPFreeSlipGenerator and STPFreeSlipData in addition to that. This aims to separate data with implementation.
• Move CUDA context parameter setting from STPMasterRenderer to STPEngineInitialiser.
• Add STPKernelMath in SuperAlgorithm+Device for easier programming.

General fixes and improvement

• Add some checkers in SuperTerrain+ to prevent user from including internal headers like STPRainDrop.cuh which has no exported symbol.
• Remove unused function parameter in STPChunkProvider.
• Improvement to documentation.
• Fix a bug when generating biomemap in column-major order which breaks spatial locality of cache.
• Make STPThreadPool constructed as an object rather than a dynamic pointer in some classes.
