0.8.1: project.json holds the version, the links, who made it and what it's built on (CMake reads it into fry_project.h and Windows' file details, which had stayed at 0.5.0); the About box lists the creators, the Help menu the website, reporting a problem and the newest version. Steadier far out: the grid's line sizes go by each pixel (not the focus, which jumps between the ground and the sky as you fly, popping every set at once), the far plane doesn't follow that focus when flying, and a wheel notch is at most twice as far as the nearest thing; the site's 0.8.1
