webgateway birds_eye_view uses thumbnail. See #10626
Big Image zooms out to fit window by default. See #8475
Removed rendering query from birds_eye_view src. See #10626

Since we are just using the thumbnail here, we don't want to make a new request to server when
the rendering settings change. Browser can reuse the thumbnail it already has
Only _load() viewport ONCE on Rendering Save/reset

This bug was causing setupTiles() to be called mulitiple times, which resulted in
many unecessary tiles being requested by the big image viewer
On rendering settings save, refresh viewer AFTER save

The saveImgRDef request fails in very big images because it happens at the same time as
many tiles are being requested. See http://trac.openmicroscopy.org.uk/ome/ticket/10660
