Pan modifier

<div

  }}
>

arguments

• onPanStart - hook fired when a pan is started
• onPan - hook fired when the pan is updated
• onPanEnd - hook fired when a pan has ended
• threshold (default: 10) - minimum touch movement needed in px to start a pan
• axis (default: 'horizontal') - axis for the pan event to be recognized ('horizontal' or 'vertical')

The hooks are passed a TouchData object which looks like:
