When rendering to an offscreen texture for `Bitmapdata.draw`,
we first render to a temporary frame buffer, and then copy the contents
of the frame buffer back to the target texture. However, this results
in blend modes being incorrectly applied - for example, rendering with
BlendMode.SUBTRACT will subtract against the framebuffer (which starts
with each pixel as 0x00000000), instead of the previous BitmapData
contents.
To fix this, we now use our texture target as the frame buffer
when performing `render_offscreen`. This ensure that we blend
over existing pixels (taking into account the `blendMode` provided
in the `BitmapData.draw` call).
When multisampling is enabled, we use a copy pipeline to copy
the existing contents of our texture to a fresh multisampled frame
buffer (the non-multisampled texture target becomes our resolve buffer).
The Adobe Animate compiler can emit a 'newclass' opcode for
a concrete class before the 'newclass' opcodes for the interfaces
it implements. As a result, we cannot rely on looking up an interface
`ClassObject` when resolving a class's interfaces.
We now store a map of exported classes in `Domain`, and use this
to lookup interfaces before their `ClassObject`s have been created.
Additionally, `link_interfaces` was failing to consider superinterfaces,
which meant that methods from superinterfaces were not being copied
into the vtable. I've fixed this along with the other changes.

The mouse picking behavior in AVM2 interacts in complicated
ways with `mouseEnabled` and `mouseChildren.` It's sufficiently
different from AVM1 that I decided to split the logic into separate
`mouse_pick_avm1` and `mouse_pick_avm2` methods.
The `mouseChildren` property is now fully implemented.
Additionally, the `click_block` tests now work correctly
under Ruffle.
Combined with the orphan-movie PR, this is enough to make
SteamBirds fully playable (though performance greatly degrades
over a course of a level).
These getters were previously calling `local_to_global`
with the unused localX/localY coordinate set to 0. Howver,
`local_to_global` does a matrix multiplication, which in general
will depend on both the x and y values. This was causing the getters
to return incorrect results when any of the `transform.matrix` values
included a non-diagonal matrix.
We now call `local_to_transform` with the real `localX` and `localY`
values.
This is needed by the Newgrounds API. We don't have the ability
to make fake requests to HTTP urls in our test frameworks,
so I haven't added any tests for this. However, I tested locally
that this allows the Newgrounds API to work (and got a medal
in Cloud Wars).
When removing a clip, first check if it has an unload event listener somewhere
it's hierarchy.
If it does, enqueue the removal to happen on the next frame, by moving it to a negative depth.
