title: Drawing a movieclip to bitmapdata moves around
body: <p>I'm trying to draw a movieclip to a bitmapdata and have it look the same as if I had just added the movieclip directly to the stage. However the result shifts around. I suspect it has something to do with the origin and bounds but can't figure it out.</p>
