* Clip away entire features by bbox. Avoid unnecessary recompression. * Move parent tile decoding in tile-join out of overzoom proper * An ever-growing cache of parent tiles * Limit the size of the cache * Remove the current reader *before* checking if we can run the queue * Clean up * Add missing #include * Add comment * When the tile-join cache fills up, evict the least recently used * Fix microsecond math * Factoring out tile-join's cache for testing * Add unit tests for tile-join cache * Update changelog and version
