The original statement i replied to was:
"Is there a way to specify mipmaps in povray or can povray do it by
itself? The only interpolation schemes i found are 'bilinear' and
'normalized distance'."
And if you think this is a perfectly valid and legit question i can only
note we have a different view here.
The correct way to ask the question Tim gave the answer for would have
been "rendering a scene with image maps gives unexpectedly bad results
for me - what can be done about this?". Instead wrong assumptions were
made how the solution for the problem should look like. My reply was
clearly referring to the way the question was asked and not personally
rude against the poster.
Note for a moment i considered an ironic reply - that next MegaPOV will
support bicubic interpolation for image maps - but i refrained from
doing so since it would have most likely been misunderstood.

I don't see anything that relates uv-mapping to scanline rendering
except that uv-mapping is very common for meshes and meshes are at the
same time the only geometry you can render with a scanline renderer.
The only thing that is required to use uv-mapping in POV-Ray is a shape
that defines uv-coordinates which has nothing to do with scanline
rendering either. It would not even need to be possible to describe the
surface parametrically - you could even uv-map an isosurface (although
this would be rather pointless).
I really don't understand why you want to force a controversy here. I
did not reject an implementation of the feature you are proposing nor
did i say it won't be added to official POV-Ray when you implement it.
I just stated by doubts about it.
