Class VFX

Creates VFX instance and start playing immediately.

Register an element to track the position and render visual effects in the area.

Remove the element from VFX and stop rendering the shader.

Update the texture for the given element.

If the element is an HTMLImageElemnt or HTMLVideoElement, VFX-JS does nothing.
Otherwise, VFX-JS captures a new snapshot of the DOM tree under the elemnt and udpate the WebGL texture with it.

This is useful to apply effects to eleents whose contents change dynamically (e.g. input, textare etc).

Stop rendering VFX.
You can restart rendering by calling VFX.play() later.

Destroy VFX and stop rendering.
