Previously we set the name of the root clip to `_level0`. Top-level
clips should actually have no name (`_root._name` returns `""`).
However, when constructing a dot path, `_level0` still gets inserted
by `DisplayObject::path` for the top-level, so that `trace(_root)`
still correctly prints `_level0`.
TODO: When `loadMovieNum` gets merged in, the proper level # needs
to be returned by `.DisplayObject::path`.
Add these methods that will explicilty coerce a value to an int,
following the wrapping behavior in the ECMAScript specs (ToInt32,
ToUInt32, ToUInt16).
This also fixed an off-by-one error for negative numbers in the
previous implementation.
These will call `valueOf` if necessary. AVM code that requires an
integer will probably use one of these (`coerce_to_i32` usually).
Properties of a display object would not reset when rewinding if
it existed in both the initial and final frames of the goto.
This fixes the weapons toggles in UFA.
When setting a variable in a function-local scope, if that variable
has not been defined in the function scope, it should be defined in
the executing movieclip's scope. Previously it would get defined
in the function's scope. Changed Scope::overwrite to Scope::set,
and modified the behavior to stop traversing and define the value
when it hits a movie clip Target scope.
Also, modified With scopes to properly add onto the end of the scope
chain.
I'm not entirely sure how to test this one - the list of errors that Flash kicks out for XML and the list of errors that `quick_xml` kicks out don't line up at all; so I just ensured that any error is a negative number (currently the one for OOM errors) and stuck whatever errors *did* match up together.
Consequently I don't know entirely *how* to write tests for this.
`idMap` is a strange property; it's only populated with nodes which had a given `id` *at the time of parsing*, and said nodes continue to be referenced even if the node is removed from the document. I have yet to find a way by which nodes can be deleted from `idMap`.
It also takes expandos, so this has to be a new retained object on the XML document. I originally considered not creating *another* `Object` impl and populating a regular `ScriptObject` with nodes, but that meant we couldn't lazy-instantiate their AVM1 side counterparts. Boo. :/
