The cursor is basically treated as if its a DisplayObject, which in practice
means that its a Sprite, MovieClip, Bitmap or Shape. Most of the examples
I've seen use embedded assets, most often a bitmap. But it can be any class
that can sit on the display list.

Of course, you're not able to access your specific instance of the class as
the CursorManager creates it internally and its not exposed. So, you have to
be tricky. Either you create a class that's a monostate (all of the
instances of the class share a common state) or have your custom class
listen for some particularly events that you're able to get into the display
list and to your class. Personally, I'd go for the monostate (more
predictable).

You'll need to create a class that inherits from DisplayObject, Sprite would
be a good choice. In your class, I'd add a static member that stores the
current "size" or "scale". And in the ENTER_FRAME event, have your sprite
copy that value into the sprite's scaleX and scaleY members. Basically, it's
manual binding (you could probably do some more traditional binding as well,
but I'm assuming here that you'd probably be using ENTER_FRAME anyway for
some animation).

Pass off your custom cursor sprite class to the CursorManager to use...
internally, it will construct an instant as necessary (based on priority of
cursors, etc.). On your end, just modify the static state (scale) as
necessary. The result will be a cursor that resizes (because the
CursorManager's instance of the class is using the same static state that
you're manipulating).

If you're embedding an SWF, just embed it and use it inside of your custom
class (add it as a child, etc.). The display list is your friend! ;-)

  If I had a custom cursor, say a swf object, is it possible to size
that object or do you have to embed each size you'd like to have?

For example, say you had a drawing app with a brush stroke, and you
wanted the cursor to reflect the size of the brush (which the user can
adjust via slider bar)
