On the interactivity issue, issue #3

> In other words, elements that have CSS shaders applied direclty or indirectly will not receive mouse events nor touch events at a minimum.  Similarly 'hover' will no longer work.
That sounds unnecessarily harsh... we don't have to turn them off, but rather just defer that issue of vertex-shader-assisted interactivity for later and currently keep the "default" behavior where touch/mouse event coordinates are relative to the element and not to the vertex shader positioning. This way, for example, a square that contains something like a water effect can still receive mouse events, without the web developer having to worry about which actual wave the user has pressed on.
