position_viewer_node()

void blender::ed::space_node::viewer_linking::position_viewer_node ( const bContext & C, bNodeTree & tree, bNode & viewer_node, const bNode & node_to_view )

static

Positions the viewer node so that it is slightly to the right and top of the node to view. The algorithm tries to avoid moving the viewer to a place where it would overlap with other nodes. For that it iterates over many possible locations with increasing distance to the node to view.
