Well commenting out assumed_gamma produces a darker image on the 'gate'
with no Display_Gamma set, so default gamma correction of 2.2 is in use.
Just to check this I changed the two planes in "Magic Gate2.pov" to the
same colour as that in "Magic Gate1.pov" and ran it both ways, without
assumed_gamma produces a noticeable difference.
I've posted a tiny file in p.b.images to show the differences.

diffuse 0 doesn't seem to make a difference but of course might once I
start changing the landscape.
The only thing I did notice was dark dots appearing on the gate then I
realised I was missing a cutaway_textures, adding it removes them as you
might expect.
