 * If both Arcade Physics circle body positions and the delta equaled zero, the `separateCircle` function would cause the position to be set `NaN` (thanks @hizzd)
 * The `CameraManager` would incorrectly destroy the `default` Camera in its shutdown method, meaning that if you used a fixed mask camera and stopped then resumed a Scene, the masks would stop working. The default camera is now destroyed only in the `destroy` method. Fix #4520 (thanks @telinc1)
 * Passing a Frame object to `Bob.setFrame` would fail, as it expected a string or integer. It now checks the type of object, and if a Frame it checks to make sure it's a Frame belonging to the parent Blitter's texture, and if so sets it. Fix #4516 (thanks @NokFrt)

+* The ScaleManager full screen call had an arrow function in it. Despite being within a conditional block of code it still broke really old browsers like IE11, so has been removed. Fix #4530 (thanks @jorbascrumps @CNDW)
