-/* CHECKED apparently c74's formula was not very carefully tuned.  It has 5%
-   deviation from the straight line for ccinput=0 (ccinput is user's curve
-   control parameter, <0..1>) at half-domain, range=1.  It generates nans for
-   ccinput > .995.
-
-   The formula below generates curves with < .000004% deviation and no nans.
-
-   Problem:  find a function f : ccinput -> cc, such that the curves will bend
-   in a semi-linear way over the ccinput's range of 0..1.  The curve function
-   is then g(x, p) = (exp(f(p) * x) - 1) / (exp(f(p)) - 1), where x is curve's
-   domain, and p is ccinput.  If, for example, the points g(0.5, p) are to make
-   a semi-linear pattern, then the solution is a function f that minimizes
-   the integral of the error function e(p) = sqr(((1-p)/2)-g(.5, p)) over 0..1.
-   Until someone does this analytically, we are left with a lame formula, which
-   has been tweaked and tested in gnuplot:  f(p) = h(p) / (1 - h(p)), where
-   h(p) = (((p + 1e-20) * 1.2) ** .41) * .91.  The file curve.gp, in the
-   sickle's source directory, may come handy, in case there is anyone, who
-   fancy tweaking it even further.
-
-   To implement this, start from these equations:
-   bb * mm ^ npoints = bb + 1
-   (bb ^ 2) * (mm ^ npoints) = ((exp(ff/2) - 1) / (exp(ff) - 1)) ^ 2
-
-   and calculate:
-   hh = pow(((ccinput + c1) * c2), c3) * c4
-   ff = hh / (1 - hh)
-   eff = exp(ff) - 1
-   gh = (exp(ff * .5) - 1) / eff
-   bb = gh * (gh / (1 - (gh + gh)))
-   mm = ((exp(ff * (1/npoints)) - 1) / (eff * bb)) + 1
-
-   The loop is:
-   for (vv = bb, i = 0; i < n; vv *= mm, i++)
-       result = (vv - bb) * (y1 - y0) + y0
-   where y0, y1 are start and destination values
