[F8] Skewing using actionscript

Hello there.
I've had a good rummage around and this question seems to have come up a couple times, but without a solution.
I did find a link to this tutorial..
http://www.senocular.com/flash/tutor...ansformmatrix/
..but that doesn't feature any code-based examples of how to actually apply the matrix transformation to an instance.
Likewise, Flash Help just has a brief entry about the flash.geom.Matrix class - minus helpful examples.
If anyone knows the basics of using the Matrix class in a simple piece of code, that'd be swell.
And all I want to do is make a leaf 'droop'...
Cheers.
