Кто нибудь рисует анимированные баннеры на html5? Ответьте на вопрос

function resizeCanvas() {			
			var w = lib.properties.width, h = lib.properties.height;			
			var iw = window.innerWidth, ih=window.innerHeight;			
			var pRatio = window.devicePixelRatio || 1, xRatio=iw/w, yRatio=ih/h, sRatio=1;			
			if(isResp) {                
				if((respDim=='width'&&lastW==iw) || (respDim=='height'&&lastH==ih)) {                    
					sRatio = lastS;                
				}				
				else if(!isScale) {					
					if(iw<w || ih<h)						
						sRatio = Math.min(xRatio, yRatio);				
				}				
				else if(scaleType==1) {					
					sRatio = Math.min(xRatio, yRatio);				
				}				
				else if(scaleType==2) {					
					sRatio = Math.max(xRatio, yRatio);				
				}			
			}			
			canvas.width = w*pRatio*sRatio;			
			canvas.height = h*pRatio*sRatio;
			canvas.style.width = dom_overlay_container.style.width = anim_container.style.width =  w*sRatio+'px';				
			canvas.style.height = anim_container.style.height = dom_overlay_container.style.height = h*sRatio+'px';
			stage.scaleX = pRatio*sRatio;			
			stage.scaleY = pRatio*sRatio;			
			lastW = iw; lastH = ih; lastS = sRatio;
