Insets are handled inconsistently at present, since menus use them to
offset the label text, whereas textlines don't. This is done because
menus need the margin to be visible when opened. However this causes an
alignment issue when menus and textlines appear in the same cedit.
Remove the offsets from menus and compensate by adjusting the bounding
boxes used for highlighting and the opened menu.
Line up menu items and textlines vertically and add a style option for
textlines to control how much padding is added.
Add a test to check the positions of objects in a cedit, since this is
more direct than the rendering tests. Add style information so that the
impact can be seen.

With fixed coordinates it is difficult to create scenes that can work on
any display size. Add a separate 'requested' bounding box for each
object and sync it when required.
With future work, this will allow scaling the nominal coordinates so
that an expo can be rendered correctly on a wider range of displays.

It is possible that positions, styling or even text have changed since
the scene was initially arranged, so recalculate the dimensions of all
objects before arranging the scene.

A menu's dimensions are currently only used for positioning the
component parts of the menu, i.e. the label, key, description and

Moving from one scene to another should not result in the scene being

It is useful to be able to edit text, e.g. to allow the user to edit the
environment or the command-line arguments for the OS.
Add the beginnings of an implementation. Future work is needed to finish
this: keypress handling and scrolling. For now it just displays the

Add support for left, right and centred alignment for text, in the
horizontal dimension.
Also support top, bottom and centred in the vertical dimension, for the
text object as a whole.
Alignment is not yet implemented for images. It has no meaning for
menus. A textline object uses a text object internally, so alignment
is supported there.
Provide some documentation to explain how objects are positioned.

Use the measurement info to write each line of text separately, thus
respecting word-wrapping and newlines.
Fix up the comment for scene_obj_render() while we are here.
Since a lineedit does not support alignment, add a special case to just
display the text if there is no measurement. This happens assuming the

In some cases it is useful to obtain more than just two bounding boxes

Use an array to obtain bounding-box information and calculate it

At present each object has a width and height and the bounding box is
implicit in that.
This is not flexible enough to handle objects which are larger than
their contents might need. For example, when centring a text object we
might want to have it stretch across the whole width of the display even
if the text itself does not need that much space.
Create a new 'dimensions' field and convert the existing width/height
into x1/y1 coordinates.
Signed-off-by: Simon Glass <sjg@chromium.org>
These coordinates are the top left values, so rename them to x0 and y0

At present we assume that each object is a simple box and that it fills
the whole box.
This is quite limiting for text objects, which we may want to centre
within the box. We need a position within the box where drawing starts.

At present a fixed position is used for menu items, 200 pixels to the
right of the left side of the labels. This means that a menu item with
a very long label may overlap the items.
It seems better to calculate the maximum label width and then place the
items to the right of all of them.
To implement this, add a new struct to containing arrangement
information. Calculate it before doing the actual arrangement. Add a
new style item which sets the amount of space from the right side of
the labels to left side of the items.
