Flash outline: on the agent's own border, in its own team colour

Review: the progress stroke was 2 px on the box edge, a pixel outside the
agent's 1 px border, and ignored neutral team colours. It now traces the
border itself and uses the outline colour AgentWidget would. The eye's
TextPainter is disposed after painting, and its ink is a named Settings
colour.
