Check if `this.video` is correct

[kalwalt]

Inside the CameraViewRenderer (getImage and image getter) there is a reference to this.video:

ARnft/src/renderers/CameraViewRenderer.ts

Line 122 in 5a66982

this.context_process.drawImage(this.video, 0, 0, this.vw, this.vh, this.ox, this.oy, this.w, this.h);

and:

ARnft/src/renderers/CameraViewRenderer.ts

Line 138 in 5a66982

this.context_process.drawImage(this.video, 0, 0, this.vw, this.vh, this.ox, this.oy, this.w, this.h);

but video is not declared or defined in the class, we have only the _video member:

ARnft/src/renderers/CameraViewRenderer.ts

Line 55 in 5a66982

public _video: HTMLVideoElement;

We need to check the correctness of this and if this may lead to some bugs.

[kalwalt]

To be clear this.video is the getters defined here

ARnft/src/renderers/CameraViewRenderer.ts

Lines 99 to 101 in 5a66982

	public get video(): HTMLVideoElement {
	return this._video;
	}

I'm wondering if this make sense or not. Could we get the _video (private) directly?
