The pto file names are obviously  generated with some "mstemp" function.
That's all fine and dandy, but how about the following? We do the random
filename thingy once per session (reinitialize on loading a new
project?). Now we have a fixed filename pto file and Makefile.

Now for the dependency, instead of specifying "project.pto" for the nona
steps we specify .mapping_of_image_0000_changed . We initialize, this
when we first write the pto file, and when we later change things, we
check all parameters that influence the nona step. If none of them
changed, we don't update the timestamp on that file. If any of them
changed, we touch the file, so that nona will run again.

We could do less "hacking" and more "let make do its job" if we extract
the minimal PTO file for nona to work with for say image1.

In my case, for image 0 that would look like: 
p f2 w4000 h1520 v200  E15.3667 R0 S30,3987,86,978 n"TIFF_m c:NONE r:CROP"
i w3872 h2592 f0 v19.4308886983727 Ra0 Rb0 Rc0 Rd0 Re0 Eev15.3666636524199 Er1 Eb1 r1.28847308425683 p0.0174682245138073 y-93.1233672191193 TrX0 TrY0 TrZ0 j0 a0 b0 c0 d0 e0 g0 t0 Va1 Vb0 Vc0 Vd0 Vx0 Vy0  Vm5 u10 n"DSC05514.JPG"

Next we compare it bit-for-bit with the older version of the simplified
pto file. If they are the same, don't update the old version. If they
are different, we replace the old version...

Title:
  Hugin doesn't allow make to skip nona.

Status in Hugin - Panorama Tools GUI:
  New

Bug description:
  I am stitching a panorama, and the blend keeps failing due to excessive overlap. Well, then I have to remove one overlapping image, and start the stitch again. As none of the images has moved, the nona step is redundant, but hugin doesn't skip it.... 
  (the issue probably is that the remapped image depends on the pto file, but the pto file only changed to note the fact that I disabled one of its sister images.
