When we receieve a nonzero 'antiAlias' parameter, we create
create a non-multisampled resolve buffer to use with WGPU.
Several tests were already requesting antialiasing, so their
output images are now anti-aliased without any changes to
the tests themselves.
If you use a `Loader` to load an SWF containing a class that shadows
an already-defined class, the class definition from the Loader SWF
will be ignoredin favor of the already-defined class. This commit
applies this log to symbol classes as well - the symbol registry for the class
should continue to point to the existing MovieClip in the parent.
This results in the child SWF instantiating the class from the parent
SWF when the child places the affected movie clip on the timeline.
This fixes a bug in Fancy Pants World 4 Part 3, where the sub-level
SWF was replacing the symbol class entry for the parent 'shipInteract'
class with the dummy clip provided in the sub-level SWF (instead
of continuing to use the correct clip from the parent SWF).
Previously, we were scaling down the source image to fit into
the smaller sourceRect, instead of cropping at the original scale.
This broke the background textures in Fancy Pants World 4 Part 2,
as the scaled-down output image resulted in a smaller rectangle
being returned from 'getColorBoundsRect'
We now crop the image by properly constructing the UV-coordinate
transformation matrix. We were also using the wrong value for the
'destPoint' y coordinate, which I fixed.
This slightly changes the image output of two tests - the new images
now more closely match the Flash output.
Calling `Hash::write_bytes` isn't guaranteed to be equivalent to a
sequence of `Hash::write_u8`.
Additionally, make sure the hash is truly prefix-free by hashing the
length first.
This was a leftover from before we started usiung vec4 everywhere
for compatibility with AGAL. There are a few specific opcodes that
don't need extension, but it doesn't depend on the destination
register.
In the process, I fixed a bug where we were clearing the depth
and stencil buffers with the incorrect value.
This makes Fancy Pants World 4 Part 1 playable to completion
(though there are still some rendering issues that need
to be fixed).
This factors out the early-resolution logic I added in `op_coerce`,
making it useable during paramter resolution as well. This lets
a static initializer reference the containing class in parameter
types, even though the ClassObject hasn't yet been initialized.
We were missing the initial 'set_skip_next_enter_frame(true)'
call, and we weren't properly clearing it in `enter_frame`.
Loaders appear to have the same behavior as MovieClips.
This makes us correctly run the first framescript for the loaded
SWF.
Despite not being MovieClips, Loader instances appear to get
the same kind of orphan handling - you can instantiate a
Loader and call 'Loader.load' without ever adding it
to a parent, and the loader will still run.
I've changed the movie code to work with a new `DisplayObjectWeak`
enum. Currently, this just supports `MovieClip` and `Loader`,
but it can easily be extended if we ever need other weak display
objects.
This also fixes a bug where we were adding the loaded MovieClip
as a child of the Loader slightly too early.
This includes the 'GetDescendants' opcode, which is used by the
the 'xml..elementName' syntax. The 'XMLList.toXMLString()
impl makes it much easier to write tests for this.
