widescreen: label areas and remaining world->screen centres

- Alt object labels and floating texts are packed into a 1024x768 area
  (push 300h/400h at 0x6272f8 and 0x60e940): widened to the render size.
- Screen centre immediates in the light/effect position list (0x41b1xx..)
  and the floating text (damage number) projection 0x41e460/0x41eaf0 now use
  the render centre; lights were offset from the player before.
