			// Adding distress to a design is simply the following:
			// 1. Create a distress pattern. This can be a bitmap or vector design. 
			//    It is simply white "random" objects on a transparent background.
			// 2. Merge the distress pattern into your existing design.
			//    Some scaling of the distress pattern may be necessary to make it look good.
			// 3. Rendering the merged design.
			//
			// Assumption: the distress pattern is white. This assumes that it will be placed on a white background.
			// If this is not the case, then you should colourize the distress to match the background or use a different distress
			// pattern.
