Soft Breaking Changes

Changes that can break existing code whose fixing is trivial:

• change clone2d(scale=...) to clone2d(size=...)
• remove shapes.StreamLines(object) becomes object.compute_streamlines()
• split mesh.decimate() into mesh.decimate(), mesh.decimate_pro() and mesh.decimate_binned() as per [#992]
• modified core.clean() after [#992]
• remove import_window() for obj files and create load_obj() by @zhouzq-thu in [#891]
• add smooth_mls_12d(..., n=0) to fix the number of neighbors in the smoothing
• modified API for mesh.binarize()
• plotter.add_hover_legend() now returns the id of the callback.
• removed settings.render_lines_as_tubes and settings.hidden_line_removal, add plotter.render_hidden_lines() method
• fix close(), close_window() is now obsolete and removed.

Hard Breaking Changes

Changes that will break existing code and need active thinking and work to adapt

• None
