I decided to start from scratch, because tuning a little bit here and there
seems not to be the best strategy.

Being aware that there may be some nonlinearities, I would like to follow
these items:

1) finding an optimal angle for the "spine"
2) adapting the lower bulb
3) adjusting the upper "loop"

(perhaps 2 and 3 should go together for overall balance, and finally, 1
should be adapted to the results of 2 and 3, but ...)

So I created a batch script which adds 0, 0.5, 1, ... 5 (in arbitrary units)
to the x coordinate of the "spine vector" (which will then be normalized 
anyway,
so the only thing that's changing is the angle) in the metafont sources,
compiles the feta font from scratch and uses this new font to typeset an
example. This took quite a long time (approximately about 75% of the
time my daughter needed to watch "twilight" on the same machine while
metafont was bleeding...)

I concatenated the pdfs to one file, which is too big for the list, so I
put it on my website:

I know that there is a spurious error on value 2, but I think that's not the
main problem. Which value looks best?
