Moving viewport when pointer out of (beyond) bounds

[crutch12]

As mentioned in #170 if you drag mouse out of viewport bounds - it stops interaction with viewport.

But if you check this example (https://pixijs.io/examples-v4/#/plugin-projection/basic.js), there is no such problem

The reason is this line: https://github.com/davidfig/pixi-viewport/blob/a23e480013022a0ba31281da1dab5408dbfb62ef/src/input-manager.js#L43

Viewport calls up method on 'pointerout' event.

So here is fast fix:

// @NOTE: Enable out of bounds mouse events working
const input = (viewport as any).input;
viewport.removeListener('pointerout', input.up);

@davidfig What about to add option like interactWhenOut: true to not call up on 'pointerout' event?

I would like to provide PR for this

Sounds good. Maybe come up with a better name for the option (although I can't think of any right now)? Or at least put in a more detailed description in the options doc.

@crutch12 , I've tried your recommended fix but it is not solving the issue. (when using noTicker: true ) With this, we are just not receiving "pointerout" event, but there is still no drag or other event when mouse is out of viewport bounds.

Are you manually calling the update method?

[makice]

Yes. I am manually updating, but since you mentioned I checked and actually I was just rendering the stage (check below):

this.drag({ clampWheel: true })
            .pinch()
            .wheel()
            .clampZoom({ minHeight: this.worldHeight / 64, minWidth: this.worldWidth / 64 , maxHeight: this.worldHeight * 2, maxWidth: this.worldWidth * 2 })
            .on('moved', () => {
                this.update(); //This fixed the problem
                this.updateStage();
            })

Thanks for the hint @davidfig :)
