Blender 3.6 introduced context property variables for drivers, which
allow context-dependent access to the active scene or view layer
without an explicit reference to a specific scene. This also allows
access to the active camera via a Scene property.
One major use case for this is accessing the camera transformation
for various potential uses like automatic level of detail. However,
the documentation isn't completely clear on how to access the
evaluated transformation, as opposed to the raw animation channels
before constraints and parenting.
This aims do fix that oversight by making some wording more clear,
and providing an easily understandable explanation of world_matrix.
