clientView
The viewport of the sub-client an agent works in, live, as the VIEW action on the agent's row of the people dropdown chose it, with how long ago the picture was taken on the toolbar.
While the tab is open it asks the engine once a second to keep the view going
(__presence.viewClient). The engine takes a small capture of that sub-client's
viewport about once a second, the same capture an agent's capture makes there,
and writes it into this session's scratch under /source/tmp/client-view/,
which the tab draws. The sub-client's own view and the user's are untouched, and
the engine stops taking pictures a few seconds after the tab closes.
