Robin,

normally, curved clipping paths are made by Bezier curves.
These start always with

x0 y0 moveto.

Then comes one path segment by

x1 y1 x2 y2 x3 y3 curveto

The path continues either by curveto or by moveto
Finally

closepath
clip

In some programs moveto and curveto are abbreviated by m
and c:
/m moveto def
/c curveto def

If the path is created by a character then one will find
true charpath
clip

Here are some examples:

In fact, any closed path can be a clipping path.

The doc contains the references for recommended books
and for a program for editing/testing.

Or do you mean the BOUNDING BOX ?
