* Solve bug related to corrupted texture tiles for certain sizes. * Regard layer settings when sampling height map. * Make Tile in to a class instead of a struct. * Memory aware lru cache. Needs cleanup. * Clean up and comment. * Clean up and comment. * Clean up * Clean up and comment. * Fix compilation error on Windows. * Specify data type explicitly in GDAL xml config files for Utah height maps. Closes #242 * Update the key type for the memory aware lru cache and use a unordered map instead of a map. * Solve pixel row size bug. * Solve initialization bug. * Add cache size as property of the globe browsing module. * Use memory aware tile cache for text tile provider. * Log GDAL errors as GHOUL messages * Add the ability to toggle tile level limiting by available data * Add ability to toggle GDAL logging * Add lock guard to memory aware tile cache * create base class rawtiledatareader that can be extended with different implementations than GDAL. * Let GdalWrapper take care of global GDAL settings. * Move iodescription to separate file * Move some functionality from gdalrawtiledatareader to rawtiledatareader * Move functionality from gdalrawtiledatareader to rawtiledatareader. * GDAL is no longer a necessary dependency for the globebrowsing module. However to read tiles, the SimpleRawTileDataReader needs to be implemented. Otherwise GDAL is needed. * Add ifdef check for GLOBEBROWSING_USE_GDAL * Implement SimpleRawTileDataReader. Currently can only read pow 2 textures. * Change ints to unsigned long longs * Limit number of texture creations per tile provider per frame * Solve linker error on windows * Fix Windows build errors * Fix crash in reading local patches * Update lodglobe descriptions * Abstract away overviews in gdal raw tile data reader * Update Mars and Moon configs. * Update screenshot script * Update ghoul version * Remove use of interaction depth below ellipsoid * Normalize direction vector * Use scale for distance swotch * Go back to use of interaction depth below ellipsoid * Fix comments on pull request. * TileProviderByLevel error does not propagate up. * Comment on mars and moon mod file * Add model space cut off level as a property * Update ChunkTile struct * Minor clean up * Go back tu constructor for ChunkTile
