How would this be implemented, by adding a hashtable to the container
with a mappings between the child actors and the additional layout
implementation specific hints?
What possibilities open up for layout management that interacts with
animated properties? In particular I wonder how it is possible to
integrate with 3D specific properties, like rotation around the x or y
axes or change of depth? By doing layout management like this, would
one need to rely on the coordinates of
actors as projected onto the stage (to reduce the problem to a 2d
one?) or would it be possible to even at this level to choose to only
do the level management relative to the immediate parent container and
operate only with this parents coordinates? (which could be neccesary
if the container is rotated around the z-axis)?
Or are the above quesitons and concerns mostly irrelevant and such
layout management something that only really applies when doing pure
2D static / fluid due to containers changing size interfaces. And
animated or more 3d use of the API would only make sense with the
fixed layout provided by the default implementation?
