Instead deduplicating separators in `RufflePlayer.showContextMenu()`
using DOM attributes, do it right in `RufflePlayer.contextMenuItems()`,
using a simpler approach.
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.
It was incorrectly declared as public method, which lead to
spurious 'missing override' errors in classes extending Array
that define a 'removeAt' method.
We don't need to perform a sync when getting the width/height,
getting or setting the 'disposed' status, or uploading to
a Context3D texture.
The Context3D change (using `copy_texture_to_texture` instead
of relying on the CPU pixels) has the added advantage of avoiding
a validation error when our source image row length isn't aligned
to `COPY_BYTES_PER_ROW_ALIGNMENT`
This dramatically speeds up the Fancy Pants World 4 loading time
(on a branch with my XML prs merged). Without this change, my
machine spends around 10 seconds on a blank white screen after
clicking 'Play'. With this change, the time spent on that screen
is reduced to around 1-2 seconds.
`SoundChannel.position` was being updated by the audio manager each
tick, but the Flash Player only updates and caches the position
when `SoundChannel.position` is accessed. In contrast, an AVM1
`Sound` will constantly update its position.
This means accessing `position` only once after a sound has
finished playing will return 0.
Fixes#9952.
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.
None of these formats can currently be implemented
correctly with wgpu, so we just use Rgba8Unorm instead.
The handling of opaque compressed textures is a little
sketchy - it should work for 'normal' SWFs that upload
an opaque BitmapData, but we might need to manually
adjust the alpha values if
