Detailed Description

An effect filter that adds a drop-shadow behind the image's content.

(This will only work on images/components that aren't opaque, of course).

When added to a component, this effect will draw a soft-edged shadow based on what gets drawn inside it. The shadow will also be applied to the component's children.

For speed, this doesn't use a proper gaussian blur, but cheats by using a simple bilinear filter. If you need a really high-quality shadow, check out ImageConvolutionKernel::createGaussianBlur()
