[iSVG] Target rectangle / right-click catch

[Antoine Q. <an...@gr...>]

Hey,

Just though of a new use for getBBox(). For the "drag.es" module, an
invisible rectangle is created to prevent unwanted "mouseout" events to
happen. We could actually do with something smaller than the
full-composition rectangle by just calling getBBox() on the dragged
element and create an invisible rectangle that would be 110% the size of
the bounding box. That would be cleaner I suppose. The invisible
rectangle would have to be dragged though, but I don't reckon it's too
much hassle.

And this is a little trick to prevent the Adobe contectual menu to
appear on right-click. This is pretty pointless as is, but one could
implement a completely new draggable-contextual menu on right click!
This is going on graougraou.com's new site.

function mouse_down(evt) {
  if(evt.getButton() == 2) {
    evt.preventDefault();
    // right-click code
}
