Add coordinates to click and dblclick events for SVG and root elements

It looks like you're saving two sets of coordinates? For example, the given code produces the following output when an SVG is clicked:

store the coordinate of the last clicked SVG

search @event
  [#click x y]

search 
  last-click = [#last-click]

commit
  last-click.x := x
  last-click.y := y

Create a default #last-click

search
  not([#last-click])

commit
  [#last-click x: 0 y: 0]

Display the last-clicked coordinate in a view

search
  [#last-click x y]

bind @view
  [#value | value: "({{x}}, {{y}})"]

Output:

(1132, 135)
(1132, 38.33333206176758)
(24.66666603088379, 135)
(24.66666603088379, 38.33333206176758)

Yeah. I can see how that's not so convenient from that example. The way I made it at the moment is SVG elements set it to the position in their local coordinate space and the root element sends clientX and clientY. All I actually want/need myself is the SVG coordinates but I thought document coordinates might be useful to someone too. Perhaps they should be relative to the application container however?

One way I could make your specific example work is by their names to svgx, svgy and clientx, clienty or similar. There's still the possibility of a similar issue arising in the presence of nested SVGs. The best solution is to specify the element you're interested in.

Thoughts?

Okay, I understand your intention now. I think maybe this is okay then. Will merge.
