Add class to <canvas>

[noamyg]

Hi,
In this example of drawing over image, the <canvas> tag gets a custom class.
Is it possible to add it to the nested <canvas> of <signature-pad>?

Thank you

Between

angular2-signaturepad/signature-pad.ts

Lines 15 to 18 in 417bba5

	@Component({
	template: '<canvas></canvas>',
	selector: 'signature-pad',
	})

and

angular2-signaturepad/signature-pad.ts

Lines 37 to 52 in 417bba5

	public ngAfterContentInit(): void {
	let sp: any = require('signature_pad')['default'];
	let canvas: any = this.elementRef.nativeElement.querySelector('canvas');
	if ((<any>this.options)['canvasHeight']) {
	canvas.height = (<any>this.options)['canvasHeight'];
	}
	if ((<any>this.options)['canvasWidth']) {
	canvas.width = (<any>this.options)['canvasWidth'];
	}
	this.signaturePad = new sp(canvas, this.options);
	this.signaturePad.onBegin = this.onBegin.bind(this);
	this.signaturePad.onEnd = this.onEnd.bind(this);
	}

it looks like it would be quite straightforward. However given that I don't use this repo anymore I'm more inclined to review/merge a PR :)
