Add idl, header and stubs for PerformanceEventTiming interface.
Two missing `PerformanceEntry` types that have come up in issues
are the `first-input` and the `event` entryTypes. Those are both
this.
Also, because both of those are this same interface, the static
methods from the parent class are difficult to implement because
of instance-specific details. Might either need subclasses or to
edit the parent and also everything that inherits from it :/
Depending on usage, `@layer` has two forms, with two different CSSOM
types. One simply lists layer names and the other defines a layer with
its contained rules.
We don't actually generate any such events ourselves. But Google Lens
will create one with the DataTransfer attribute set to that of any drop
event we send it.
This is an AudioNode representing the final audio destination and is
what the user will ultimately hear.
This node is used as one of the connecting nodes in athenacrisis.com
Add a placeholder for the interface without anything backing it for now.
This implements most of the CloseWatcher API from the html spec.
AbortSignal support is unimplemented.
Integration with dialogs and popovers is also unimplemented.
This fixes https://html5test.com/ as previously an exception was being
thrown after trying to access this attribute which would then result in
a popup about the test failing (and none of the test results being
shown).
As with all other current audio nodes we still need to wire up the
inputs and outputs so it can be properly used in an audio context - but
this is enough to implement the public IDL interface.
EventSource allows opening a persistent HTTP connection to a server over
which events are continuously streamed.
Unfortunately, our test infrastructure does not allow for automating any
tests of this feature yet. It only works with HTTP connections.
An AudioNode is the fundamental building block used in 'Audio
Contexts'. In our immediate case, the audio node we are working towards
implementing is an oscillating source node.
