Added a grace-period animation (as well as a nice pattern for rendering
other animations if needed) that pauses the game for about a second upon
death right after respawn, with a closing circle towards Bonzo giving
the player time to prepare and directing their attention to where Bonzo
is now.

Gameplay wise, this offers an improvment to respawn by removing the
feeling of 'oh no where did I respawn bah I just died again'.
Added 'getReady' image to respawn, boosted the time from 1 second to
about 1.5 seconds, and added drawing code to fullscreen mode.
