I think that was done long ago; I know that *I* reported it in the distant past,
but probably not to the bug-reports page.
So I did another test... and confirmed that the problem is still there :-( I'm
almost(?) sure that one of the v3.7 - v3.8 'development' versions in the past
had fixed this behavior...if only temporarily, it seems.
One example here uses the 'onion' pattern; the other uses an
image_map-to-function:
#declare somb =
function{pigment{image_map{jpeg "test image.jpg" once interpolate 2}}}
then...
function 1000, 1000 { somb(x,y,z).gray}
Of course, this weird effect can be fixed after-the-fact, with appropriate
negative scaling etc...
scale <1,1,-1>
translate <0,0,1>
