The FastBlur effect softens the source content by blurring it with algorithm which uses the source content downscaling and bilinear filtering. Use this effect in situations where the source content is rapidly changing and the highest possible blur quality is not needed.

Often, the InnerShadow item is anchored so that it fills the source element. In this case, if the HorizontalOffset and verticalOffset properties are set to 0, the shadow is rendered fully inside the source item.
