Use concat (+=) rather than join

Lines 1 to 28 in b8d5bd7

	export class PathBuilder {
	private array: string[] = [];
	public moveTo(x: number, y: number) {
	x = clamp(x);
	y = clamp(y);
	this.array.push(`M ${x} ${y}`);
	}
	public lineTo(x: number, y: number) {
	x = clamp(x);
	y = clamp(y);
	this.array.push(`L ${x} ${y}`);
	}
	public closePath() {
	if (this.array.length > 0) this.array.push('Z');
	}
	public toString() {
	return this.array.join(' ');
	}
	public concatPath(pathBuilder: PathBuilder) {
	return this.array.concat(pathBuilder.array).join(' ');
	}
	}

Today making += is faster than join

Indeed, string concatenation appears to perform better than using join
