By passing ee.getParentNode() you will be 'bypassing' the transform on
'ee'. So if the rectangle is rotated by setting it's transform attribute
(as opposed to a parent's transform attribute) then your mapping of
ClientX/Y will be to the wrong coordinate system. The 'x'/'cx' & 'y'/'cy'
attributes are in the local coordinate system of the element (after it's
transform has been applied).
