3.7.0.beta.11b.icl8.win32
Only did a little checking about this but looks like only image_map is
affected, not other transparent things using transmit or filter in colors,
and I didn't find any mention of it after a quick search. The script below
uses the sample test image included with POV that says POV-Ray on it (in
white) along with letter pairs in black for each quarter section: TL, TR,
BL, BR (I'll post similar resulting rendered images from 3.6 and 3.7 at
beta-test.binaries to show which image file I'm talking about, but others do
same anyway).
Also, although this uses clipped_by here, I first noticed this in a CSG
difference used to hollow the sphere so the shell would have thickness but
it seems to only be about the image_map+transparency+light_source somehow.
camera { location -3*z }
light_source { <10,10,-10>, color rgb <1,1,1> }
sphere { 0,1
clipped_by {
box { 0,1 inverse }
}
pigment {
image_map {
gif "test.gif" // test image
map_type 1
transmit 4, 1
}
}
rotate <30,150,0>
}

Just realized that GIF should probably be a PNG instead, since file format
been changed for the more recent POV distributions. Sorry for any confusion
due to that.
