Howard Trickey 49aa701645 Add profile control parameter to Bevel.
Parameter controls concavity / convexity.
    <.25 means: concave inward
    .25 means: straight slanted
    >.25 means: concave outward
    .5 means: circular (the default)
    1 means: straight along original sides
For now, there is a hard lower limit of .15
because more work is needed to get decent
results in the range below that.

The profile is actually a superellipse, and the
parameter is 1/4 of the exponent in the implicit equation
for a superellipse, except at the extreme values of 0 and 1.
