fix [3095607] Gingerbread screen turn-on animation does not show the last frame

always redraw the screen entirely after the power-on animation, because:
- the animation may not run (ie: on the emu)
- the animation may not contain the video planes
- the interpolation may not be perfect and not land exactly on the last frame
