* Debug mode: no longer enables the DebugOverlay (F3) by default, but does now insert the current FPS counter into the window title bar. * ui.Frame: set a default "mostly transparent" BG color so the frame background doesn't render as white. * Add the MenuScene which will house the game's main menus. * The "New Level" menu is first to be added. * UI lets you pick Page Type and Wallpaper using radio buttons. * Page Type: Unbounded, Bounded (default), No Negative Space, Bordered * Fix bugs in uix.Canvas to fully support all these page types.
