Provide an implementation for textlines in the scene code, so that they
are displayed correctly. Provide a way to have a border around the
textline, with the internal part being the same colour as the
background. This looks more natural.

This object needs special handling when it is opened, to set up the CLI
and the vidconsole context. Add special support for this.

So far only menus have a background. When other object types are
rendered, they may have a background too. Make this code more generic
so it will be usable by new object types.

Add a command to read edit settings from CMOS RAM, using the cedit
definition to indicate which registers and bits are used.

For some operations it is necessary to process all objects in an expo.
Provide an iterator to handle this.

Add a new 'cedit' command which allows editing configuration using an
expo. The configuration items appear as menus on the display.
This is extremely basic, only supporting menus and not providing any way
to load or save the configuration.

When a menu is opened, it must be displayed over all other objects in
the scene, so that all its items are visible.
Handle this by drawing the menu object a second time, after all other
objects have been drawn. Draw all of the objects which are dependent
on the menu object.

When a popup menu is closed it shows only the selected item. When it is
open it shows a background and all items, with a highlight that can be
moved between the items.
Add the drawing logic for this.

It is a pain to manually set the fonts of all objects to be consistent.
Some spacing settings are also better set globally than by manually
positioning each object.
Add a 'theme' to the expo, to hold this information. For now it includes
only the font size.

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.
