Utils

Dtk_OffsetSurface : Added ComputeOffsetedSurface() function, which computes and returns a result surface with offset applied. Depending on the input surface, the result may be a Dtk_NurbsSurfacePtr, but also a Dtk_PlaneSurfacePtr, Dtk_ConicalSurfacePtr, Dtk_CylindricalSurfacePtr, Dtk_ToroidalSurfacePtr Dtk_SphericalSurfacePtr or LinearExtrusionSurfacePtr.
