The XRCompositionLayer interface of the WebXR Device API is a base class that defines a set of common properties and behaviors for WebXR layer types. It is not constructable on its own.
Several layer types inherit from XRCompositionLayer:
XRCompositionLayer itself inherits from the general XRLayer class (which inherits from EventTarget).
XRCompositionLayer.blendTextureSourceAlpha A boolean enabling the layer's texture alpha channel.
XRCompositionLayer.layout Read only The layout type of the layer.
XRCompositionLayer.mipLevels Read only The number of mip levels in the color and texture data for the layer.
XRCompositionLayer.needsRedraw Read only A boolean signaling that the layer should be re-rendered in the next frame.
Inherits methods from its parent, EventTarget.
XRCompositionLayer.destroy() Deletes the underlying layer attachments.
