PDF import changes: FilledCurve instead of polygons


Hi,

up to version 7.01 it was possible to

ImportString[ExportString[expr, "PDF"], "PDF"]

and get a vectorized polygon representation of expr, which was mighty
useful for annotations in 3D, as these polygons could easily be
transformed to their 3D equivalents.

In version 8 one gets FilledCurve objects, which are brilliant in 2D,
but which cannot be used in Graphics3D[].

Is there any way to
a) revert to the old behaviour or
b) convert a FilledCurve to a 3D object or
c) get vectorized expressions as 3D objects with another method?

Any suggestions are welcome.

Kind regards,
Yves
