Since this is under review now, can you also take a look at exposing a mouse down event too? The click event that is available fires on mouse up. I'm also in need of the mouse down event.

Alternatively, maybe expose a reference to the canvas directly so you don't need to expose events one at a time?

What I'm trying to do is implement a mouse scroll wheel zoom feature, and a mouse drag-to-pan feature, for an image viewer component that I made. I need the mouse-down event so that I can detect if a user is holding down their mouse button. I need the scroll wheel event so that I can let the user scroll to zoom in or out.

Thank.
