Framebuffer effect issues in Skies Of Arcadia

Framebuffer effects in Skies Of Arcadia don't quite work right in nulldc (r56 
tested) - what should happen is that the current image should be captured and 
then used like a texture in the special effect. What actually happens is that 
the captured image is stretched horizontally, so only the left half of the 
image is visible.

This is most reproducable in the first boss battle, where the effect is seen 
three times in quick succession (after the bull first rears up and the battle 
is triggered, the second time the bull rears up and then a scene transition 
from the bull to the battle field). I've attached the nearest save game (walk 
down the narrow corridor, through the door, down the ladder and through the 
door to get to the boss).

Proper behaviour is here (4:30 onwards):
