Subject: [PATCH 1/7] - in camera.py and cameras.py:   avoid importing the full
 vtk namespace (speed)   rename old 'clippingRange' -> 'clipping_range'  
 rename old 'focalPoint' -> 'focal_point' - render.py   remove import
 "matplotlib.pyplot as plt", this looks like a genuine bug and   correct
 close() method   avoid setting size='full' as this is poorly dealt with in
 vtk - add "actor._mesh.transform = None" in "if isinstance(actor._mesh,
 VedoVolume)"   as future vedo release will need this - settings.py:   set
 WHOLE_SCREEN = False - fix output path in examples/screenshot.py and video.py
 - pyproject.toml:   a newer version of "morphapi>=0.2" seems to be needed
