Computes the absolute deflection value depending on the type of deflection in theDrawer:
In case of the type of deflection in theDrawer computed relative deflection for shape is stored as absolute deflection. It is necessary to use it later on for subshapes. This function should always be used to compute the deflection value for building discrete representations of the shape (triangualtion, wireframe) to avoid incosistencies between different representations of the shape and undesirable visual artifacts.
