Panning moves the entire UI, not just the content area. The toolstrips and the content move as a single entity. It should feel as though the entire browser is being moved by your finger. | |||
The <code><canvas></code> display surface displays the visible part of the web content. However, a little more than the visible area is actually drawn into the <code><canvas></code>. This allows panning to immediately show parts just "off screen" as the area moves. Also note, the entire web content is never drawn into the <code><canvas></code>. That would seriously slow down performance. | The <code><canvas></code> display surface displays the visible part of the web content.
