AtkImage implementors should always implement atk_image_get_name and
atk_image_get_description I think, even if the information is partly
redundant, for consistency.

I think this is not a good idea, since the names scroll, don't they?
Implementing AtkText for scrolling items is a real mess.  Since the
names are unattributed text,
it may be better just to use AtkObject's atk_object_get_name here.

Yes.  It may be that these colors should be selected from the GTK+
theme.
