* Removal of ChunkRenderer, ChunkedLodGlobe, ChunkCuller, chunklevel evaluator, culling classes, layershadermanager, GpuLayer, GPUData, ChunkNode, Grid, BasicGrid, Chunk files, Angle, AABB classes, PointGlobe, Ellipsoid, TileSelector, tiledatatype, iodescription, simplerawtilerreader, rawtilereader * Less dynamic allocation for SkirtedGrid, LayerManager, RenderableGlobe, TextureUnit * Clean up memory management in RawTiles * Code simplification * Optimize shader uniform setting * Introduce UniformCache * Callback simplification * Turn ChunkNode into a struct * Use a MemoryPool to organize all ChunkNodes rather than use unique_ptr and the necessary memory allocation * Collect draw calls * Consolidate fragment shaders between local and global renderer * Shader cleanup and optimization * Update CMake to not include included shaders * Integrate traversal function into the looping * Replace std::queue with std::vector * Merge TextureContainer into MemoryAwareTileCache * Lazy computation of chunk bounding boxes * Memory management of LayerGroup * Remove class hierarchy from tileproviders (temporaltileprovider not working yet) * Remove PBO classes * Chunk status stored in Chunk * Don't create a copy of the ChunkTilePile * Enable culling by projected area on default * Have raw tile reader return a Tile instead of a shared_ptr to a tile * Start making GDAL mandatory * Increase the default lod scale factor to 15
