title: CALayer shadow with Spread & Size attributes?
body: <p>i'm struggling creating a drop shadow around a CALayer. For the effect i'm trying to achieve i need to have access to the "intensity" of the shadow. Somehow like the "spread" slider in Photoshop's Layer Styles. I think the "ShadowRadius" property of CALayer is equivalent to Photoshop's "Size" slider.   </p>
  
  <p>Any suggestions? Is maybe a radial gradient an option? </p>
