"""Provides the object code for the DrawingView object (OBSOLETE).

This module is obsolete, since the Drawing Workbench stopped
being developed in v0.17.
The TechDraw Workbench replaces Drawing, and it no longer requires
a `DrawingView` object to display objects in a drawing sheet.

This module is still provided in order to be able to open older files
that use this `DrawingView` object. However, a GUI tool to create
this object should no longer be available.
