# Button (filter, event)

A button. Surrounds its child with a raised shadow, and generates an event when clicked.

Behavior
  On a down-click, the shadow becomes recessed; restores the raised shadow on an up-click or chord-abort, and generates an event if the mouse is still within the button on the up-click.
Shape
  The natural shape of its child (i.e., with no shrink or stretch), plus the border around the button.
