→Panning/Zooming
Pannning 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></canvascode>. 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></canvascode>. That would seriously slow down performance.
While panning moves the entire UI, zooming only affects the content area. However, the content are does "grow" when zoomed, so the right toolstrip seems farther to the right then when the content is not zoomed.
