<!-- ##### SECTION Title ##### -->
AtkComponent

<!-- ##### SECTION Short_Description ##### -->
The ATK interface provided by UI components which occupy a physical area on
the screen.

<!-- ##### SECTION Long_Description ##### -->
<para>
#AtkComponent should be implemented by most if not all UI elements with
an actual on-screen presence, i.e. components which can be said to have
a screen-coordinate bounding box.  Virtually all widgets will need to
have #AtkComponent implementations provided for their corresponding
#AtkObject class.  In short, only UI elements which are *not* GUI
elements will omit this ATK interface.
</para>
<para>
A possible exception might be textual information with a transparent
background, in which case text glyph bounding box information is
provided by #AtkText.
