Performance test with AS3 and thousands of particles

<p>I've never experimented with using bitmapData and the copyPixels() method to increase performance when animating a large number of particles so I thought I'd have a quick play to see what could be achieved. <p /> This demo has 2000 particles that bounce off the walls, have gravity and friction and are given a small motion blur and it manages a nice 24/25 fps (see the stats). <!--more--></p>
