It could be that "native" isn't required anymore and everyone needs to
externally link.  Don't know for sure.  My understanding is that the
public APIs need to be there because the compiler parses the library.swf
to build up the class definitions the compiler will use when compiling
your app.  You can see from [1] that most methods are stubs.  I have no
idea why some methods have bodies or why there are private methods.  It
might also be used internally for test generation.

I don't think there is a way to override a built-in player class.  The
ApplicationDomain rules would cause me to expect that all classes in
playerglobal.swc are already in the ApplicationDomain before your SWF
loads and first-in wins.
