Find views (instance of
joint.dia.ElementView) under a certain point in the paper.
point is an object with
y properties. Returns an
array of views whose bounding box contains
point. Note that there can be more then one views as views might overlap. Note there is a difference between
this method and the joint.dia.Graph:findModelsFromPoint. A bounding box of a view can be different than the area computed by an element model
For example, if a
<text> SVG element in the shape is positioned relatively and shifted down below the normal shape area (e.g. using the JointJS special attributes), the bounding box
of the view will be bigger than that of the model.
