Debugging our app with the Color Blended Layers option
All that red on the screen indicates a high level of blending on the text labels, which is not
surprising because we had to make the background transparent to apply our shadow effect.
That explains why the renderer utilization is high.
What about offscreen drawing? Enable the Core Animation tool's Color Offscreen-
Rendered Yellow option (see Figure 12.11).
