- changed the UI font, made it a bit smaller - fixed the text positioning in the status bar - added ThreadPool::clear to remove all pending jobs - fixed the TargetCamera matrix calculation to avoid singularities when the camera looks straight up or down. - fixed ommited normalization in TargetCamera's matrix calculation - added paths/sec display in the status bar
