Optional
liveOptionally provide an existing canvas element, on which the Live RenderTarget will be rendered.
If this is not provided, CameraKit will create a new canvas element which can be added to the DOM.
Optional
renderBrowsers optimize tabs when they are hidden - for example, by pausing the execution of requestAnimationFrame callbacks.
If you need the CameraKitSession to continue rendering even when the tab is in the background, set this to true. There is a small performance penalty, and it's a good practice to only render in the background if absolutely necessary.
Options available when creating a CameraKitSession.
