* Simplest possible PBO implementation. * Add PBO class * TileLoadJob owns raw tile data * Working on a soluton to cache textures and reuse them * PBO and cached textures working for one texture type. Color textures. * Threadpool for tile requests uses LRU cache as queue * Remove framesUntilRequestFlush * Clean up * Clean up * Use prioritizing concurrent job manager * Use TileTextureInitData to initialize RawTileDataReader. * Class TextureContainer owns the textures to use for tiles. * Using TileTextureInitData to determine if new caches need to be created. * Remove WriteDataDescription * Remove TileDataLayout * Rendering many different layer types again * TileProviderByLevel gives layergroup id to tile providers * Comment away use of PBO * Erase unfinished requests to make room for new ones * Enable choice of PBO or not. * Enable resetting of asynctiledataprovider * Add the ability to use PBO and also load to CPU * Update ghoul * Solve culling issue. * Texture pointer of Tile is now a raw pointer. Currently break single image tile provider and text tile provider. * Add gpudata * Move fetching of shader preprocessing data to LayerManager * No comparisons to determine shader recompilation. * Show the tile cache size in the GUI * Clean up and comment. * Solve bug where float is interpreted as NaN * Enable ability to blend between layers again * Fix single image provider * Fix windows build error * Fix OSX compile issue. * Some clean up * Showing correct texture data size * Enable use of text tile providers again. No backgroupd image path however. * Change cache size from GUI * Clean up * Solve osx compilation error. * Update ghoul * Make it possible to switch between PBO and not during runtime. * Enable resetting of tile datasets * change function module in moduleengine to identify module by name * MemoryAwareTileCache is no longer a singleton * Update ownership of properties for globe browsing * Logging info about resetting tile reader. * Logging info * Fix requested changes * Fix some compile warnings. * Fix compilation warnings * Add ability to blend values with blend parameter. Also define settings through lua dict. * Fix some comments on pull request. * Change formatting * Change formatting * Change formatting * Fix pull request comments. * Those are details * Make Mercury great again. * Make Earth great again. * Solve conflict * Test to sometimes use valueblending and sometimes not * Not always use value blending * Update ghoul * Change from auto to explicit type. * Update test for LRU Cache * Include algorithm.
