Thanks to everyone for their suggestions, especially Chris Kohlhardt.
No one gave me the exact answer I was looking for, but eventually I
figured it out.
Here is my new function for checking if a point is within a click region:
<method name='preciseContainsPt' args='inX,inY'>
<![CDATA[
return this.__LZmovieClipRef.hitTest(inX,inY,true);
]]>
</method>
Personally I think this is how containsPt should be implemented, and
I'll file a bug making that suggestion.
If you use this function, please note that unlike containsPt, which
takes an x and y relative to itself, preciseContainsPt takes an x,y
relative to the canvas.
