title: Are there any libraries providing mouse-driven zoom/pan for pure AS3 projects?
body: <p>Today I wanted to add mouse-driven zoom and pan functionality to a pure AS3 project - something like the Google Maps interface. I was surprised that I couldn't find a good package or library to do this already - I'm using FlashDevelop rather than Flash CS3, so the <a href="http://bryanheisey.com/blog/?page_id=18" rel="nofollow noreferrer">nice VCam tool available as an FLA</a> is no use.</p>
  
  <p>There's nothing very complicated involved in implementing zoom/pan, although it can be fiddly and time-consuming to get right, but since zooming and panning are pretty common things to want to do I wondered if anyone could suggest a 'correct' way to do this in the Flash world, or a good library available that I haven't been able to find.</p>
