Override this method to handle the behavior
of the view provider depending on changes that occur to its properties
such as line color, line width, point color, point size,
draw style, shape color, transparency, and others.
This method updates the texture and pattern if
the properties `TextureImage`, `Pattern`, `DiffuseColor`,
and `PatternSize` change.
Parameters
----------
vobj : the view provider of the scripted object.
This is `obj.ViewObject`.
prop : str
Name of the property that was modified.
