Provide a way to set the full dimensions of objects, i.e. including the
width and height.
For menus, calculate the bounding box of all objects in the menu. Set all
labels to be the same size, so that highlighting works correct, once
implemented.

We currently have just a 'hide' property for each object. In preparation
for adding more properties, convert the struct to use a flags value,
instead of individual booleans. This is more extensible.

A scene is a single screen within an expo. It is possible to move between
scenes but only one can be displayed at once.
Add a basic implementation.
