-b box : store the rectangular box as a Fcurve
x1 : first corner (x coordinate)
y1 : first corner (y coordinate)
x2 : opposite corner (x coordinate)
y2 : opposite corner (y coordinate)
in : input (Fcurves)
out : output (Fcurves)

This modules crops a set of Fcurves with a rectangular box. All connected
components of the intersection of the box with the input curves are
stored in a Fcurves structure (which may be NULL).
The intersection points at the border
of the box are not computed: only the points of the
input curves lying inside the box are kept.
-b option produces an additional Fcurve that represents
the croping box given as an input to the module.
