Comment 4 for bug 1067166

Is there a particular attachment to the vitruvian man style accessibility symbol? I know Apple and Gnome use it (not sure who copied who) but the overall recognition level of it is very low. Could we use a mono version of the accessibility team logo? https://wiki.ubuntu.com/Accessibility/HeaderMain?action=AttachFile&do=get&target=accessibilityteam.png
