deliteful widgets using pointerdown react equally to left, middle and right click.

All widgets using pointerdown respond equally to left, middle and right click.

I think they are all here: ToasterMessage, Switch, StarRating, Slider, SidePane, ViewIndicator, SwapView.

If we take a native widget such as a checkbox, it doesn't respond to right click. I believe our widgets should be checking which button was pushed before reacting, or some at least: for example as a user I'd expect Switch to behave like a checkbox.

@wkeese This may apply to delite/HasDropDown

OK. So for mouse events we should respond to left-click only, but we also need to respond to touch events (which don't have a concept of left or right). Have to figure out how to test for those two cases.

For touch events, it's specified here: http://www.w3.org/TR/pointerevents/#chorded-button-interactions.
I checked and dpointer is implementing it.

Sounds like event.button === 0 will do what we want for both touch and mouse.

Native checkboxes, radio buttons and links respond to both left and middle click, so i'd say button === 0 or 1.
