class GeometryDriver from TPrsStd inherits Driver from TPrsStd
---Purpose:
-- This method is an implementation of TPrsStd_Driver for geometries.

    returns mutable GeometryDriver from TPrsStd;
---Purpose: Constructs an empty geometry driver.    
    Update (me : mutable ;
           aLabel      : Label from TDF;
	   anAISObject : in out InteractiveObject from AIS)

    --- Purpose: Build the AISObject (if null) or update it.
    --           No compute is done.
    --           Returns <True> if informations was found
    --           and AISObject updated.
