Fix aspect ratio bugs
- ICCCM says: > If a base size is not provided, the minimum size is to be used in its place and vice versa. i3 didn't obey the "vice versa" part. Min size and base size are both saved without replacements in window_update_normal_hints, floating_check_size makes the needed replacements if either was not provided. - Aspect ratio is now saved correctly in manage_window because window_update_normal_hints is called. - i3 didn't save the aspect ratio if the window conformed the given aspect ratio range when handle_normal_hints was called. If the window was resized to a size outside of the given bounds, i3 didn't correct it. - Aspect ratio now affects only tiling windows, like the rest of the normal size hints - The aspect ratio calculation is now done without a loop A real life example of how these changes affect the workflow: An mpv window, when playing a video, sets its min == max aspect ratio during mapping. i3 ignored these hints. When resized, the window's aspect ratio was not preserved. With this commit, resizing floating mpv windows will always preserve the aspect ratio.next
