* get image returns optional<Mat> instead of unique_ptr<Mat> * introduce complexity * rename image load function * add example for a basic reader for binary image files * fix windows build? * add a status bar underneath the menu bar * use status bar in custom_0 example app * clang formats * packing w/ pragma push * add "Save As" functions to image views * resize over reserve * rm local override uri * add simple thread pool * rename to simple_thread_pool * get rid of useless renderlib * document version inc * extract hardcoded values to in-header * clang format patch * clone registered image in custom_0 * document binary-file header * minor fixes * clang format * rm unused render cmake
