Ref: #8086
Signed-off-by: Ralph Sennhauser <ralph.sennhauser@gmail.com>
This commit primarily corrects an inaccurate comment and resolves a
hidden bug in the VisualActor shadow logic, while preserving the current
behavior.
Previously, the DisableShadows option removed both casting and receiving
shadows. However, the internal logic ignored this setting in some cases,
causing shadows to appear even when explicitly disabled in XML
templates.
This change introduces the ability to control CastShadows and
ReceiveShadows independently via template settings, defaulting both to
true unless explicitly specified.
In addition, previews are updated to receive shadows but not cast them,
improving visual volume effects without affecting lighting behavior.
Since 1bccfef6fb the `CSimulation2` uses the `std::shared_ptr` only in
the constructor and stores a `ScriptContext&` (inside it's members).
That's a bit dangerous: A caller might think `CSimulation2` takes
ownership of the `ScriptContext`.
With this commit the caller has to pass an `ScriptContext&` to the
constructor.
