+
+@itemize
+@item Composite Blur provides several highly optimized blur algorithms
+including Gaussian, Multi-Pass Box, Dual Kawase, and Pixelate.
+@item Composite Blur provides multiple blur effects to give a different look
+and feel to the blur including Area, Directional, Zoom, Motion, and
+Tilt-Shift.
+@item Composite Blur also allows setting a Background Source so that it can
+properly composite blurred masks, allowing you to properly layer blurred
+sources.
+@item Finally, Composite Blur provides an option to mask where and how much
+blurring occurs on the source via Crop, Rectangle, Circle, Source, and Image
+masks.
