rubber-band move text, gammas, energy-sum, etc

test and document SQ: 4D SDB search in 4dg8r

[ double matrix inversion again? ]
[ Fitting energies - chisq > chisq1 due to moving peaks ]

move function comfil from esclev.c and gf3_subs.c to util?
   - get rid of extern FILE *infile etc. in other modules?

---------------------
ss, rs into escl8r/levit8r/4dg8r help

ask, askfn : set Cancel button label in special cases??

gls/esc/lev/4dg & motif versions - save ~, especially on exit?

***  hpk in ss/rs - is it needed / used?

Dialogs:

Add level  -  E, J, pi, (name of new band)
Add band?
Add text?
new .esc/.lev/.4dg file?
      - files, bkgnd, ecal, effcal, fwhm & shape
fit - intensities, energies, both
    - level_energies?  -- need to split get_fit_lev() out of src/libs/gls/fitl.c
    - width parameters?
Settings?  - e.g. turn bell on/off

spectrum display setup:
 -  apply/reset/cancel, toggle on-off applies typed values, other not-so-nice features
     - only way to fix is to remember entry values?
 - remember "disp diff sp" when changing "disp calc. sp"
 - hide, rather than delete, the dialog on Ok or Cancel?

change spectrum zoom mode to be like ex/xa command

fit level energies does not always scroll listed output

fit width params does not work!
