Previously, the `ApplicationDomain` constructor ignored its argument,
instead of constructing a new domain with the specified domain as
the parent.
Additionally, we were incorrectly executing code with
`Activation::from_nothing` in several places, causing
`ApplicationDomain.currentDomain` to return the system domain
instead of the correct parent domain. I've introduced a new method
`Activation::from_domain`, which allows explicitly passing in the
domain. Internally, we now store an `Option<Domain>`, and panic
when calling `caller_domain` with a `None` domain. Several places
in the codebase have been adjusted to pass in the correct domain.
The XML call handler is implemented as 'new XML(arg)',
so we get all of the related string coercions for free.
Our various native tables are starting to get somewhat wasteful -
if we add any more, we might want to consider a more compact
representation.
This is a very large diff, but most of it comes from test files and
output.
This PR ads partial support for the following Stage3D shader features:
* Normal (square), rectangle, and cube textures
* Varying and temporary registers
* Lots of opcodes
The combination of these allows us to get a raytracing program
fully working in Ruffle. I've included it as image test.
Currently, this test is very slow (about 90 seconds on my machine),
as the code I'm using (https://github.com/saharan/OGSL) includes
its own shader language and compiler. THe raytracing demo
first compiles its own shader language to AGAL, and then starts
rendering the scene.
Limitations:
* Many opcodes are still unimplemented
* Most non-default texture options (e.g. mipmaps) are not implemented
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.
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).
