The Flash Player 'Matrix3D.recompose' method throws exceptions under
certain circumstances with the "quaternion" orientation style.
I haven't yet figured this out yet, so I've marked that case as a stub.
All of the implementations are based on the OpenFL code, with some
tweaks to match Flash Player's behavior.
TextFields have a very unusual behavior - if they are selectable
and have `was_static`, they *block* the dispatch of mouse events when
they're targeted (not even the Stage will receive the event).
This only occurs when the TextField is actually targeted
(which requires mouseEnabled=true). With mouseEnabled=false,
the event will be dispatched with an ancestor as the target,
following the usual logic.
Also, TextFields now properly propagate mouse picks to
their parent if mouseEnabled=false. Previously, setting
mouseEnabled=false for a TextField made all mouse picks
cause a miss on it. This was the cause of the Turbo Kids
regression.

This can actually affect runtime behavior - if the return type is
declared as 'int', then an instance of a custom class will get
coerced to 0 when returned by the function.
'Plants vs Zombies Demo' relies on this - it has a function which
incorrectly returns an object instead of an array index, but the
value gets silently coerced to 0 under Flash Player.
This is based on URLLoader, and doesn't actualy 'stream' data -
it all becomes available once the request finishes. However, this
is good enough to get Sniper Team working.
We now run all of the completion logic (including adding
the new DisplayObject as a child) in `Loader::movie_loader_complete`.
Previously, some of this logic was run from `Loader::preload_tick`,
which meant that loaded images did not have the logic run.
Also, `BitmapData` and `Bitmap` instances (with corresponding AVM2
objects) are now properly constructed for loaded images.
In a previous PR, I introduced an optimization that used
`copy_texture_to_texture` to copy directly from a BitmapData GPU
texture to a Stage3D GPU texture.
Unfortunately, this optimization is incorrect. A BitmapData GPU
texture can be modified at any time by normal AVM2 code - in
particular, in might be modified before we submit the encoded
`copy_texture_to_texture` command. This shows up in Sniper Team,
which re-uses BitmapData objects for multiple distinct textures.
The previous 'optimization' resulted in the wrong BitmapData contents
getting uploaded to a texture (since it was changed before the copy
command was submitted).
This matches the Flash Player documentation. Since we were
manually traversing the displayobject hierarching when firing
the event, we ended up firing duplicate events to parents
because bubbling was enabled.
