Impossible in theory doesn't mean it's not often doable in practice.  In 
addition, I suspect you'll find that if you think carefully about your 
theoretical reasons for impossibility it's not so cut and dry as you 
might think, as the main problems are with the psychology of the viewer 
rather than mathematical.

True enough, although that changed a bit over the course of the thread. 
  For example just now you said "there are strong theoretical reasons 
for why it should not be possible, ever".  That's pretty dang close to 
saying it's impossible.

You misunderstand, it's not that people think you're too stupid to 
figure out how to do it, it's that they think you're more than capable 
of doing it but have convinced yourself that you can't and refuse to 
hear otherwise -- hence the frustration.  For instance, both Darren and 
nemesis provided sketches of descriptions of how to do it manually, 
which you promptly disregarded as well beyond your skill level.  If you 
sat down, watched some tutorial videos on Youtube for creating seamless 
textures, and practiced with GIMP for a few days, you'd probably soon 
find that you could create reasonable textures much of the time (given a 
few hours of work per texture of course).

As for automated algorithms, how trivial it is depends on how 
sophisticated the textures you need are.  GIMP's crossfade algorithms is 
totally trivial and will work well in simple cases.  For more 
sophisticated situations something like Adobe's content aware fill with 
cyclic boundary constraints would probably do quite well (not that that 
provide the source code though, so it's of little use to you).
