Binding event handlers to Surface

[nornagon]

It doesn't seem to be possible to bind event handlers to the root Surface object. Given the following, the mouseDown handler never gets called:

<Surface onMouseDown={@mouseDown}>...</Surface>

I've used something like the following to achieve the same effect:

<div ref='canvas' onMouseDown={@mouseDown} style={{padding: 0, margin: 0, border: 0}}>
  <Surface>...</Surface>
</div>
