 *--shadow-exclude-reg* 'GEOMETRY'::
 	Specify a X geometry that describes the region in which shadow should not be painted in, such as a dock window region.  Use `--shadow-exclude-reg x10+0-0`, for example, if the 10 pixels on the bottom of the screen should not have shadows painted on.

 *--backend* 'BACKEND'::
 	Specify the backend to use: `xrender` or `glx`. GLX (OpenGL) backend generally has much superior performance as far as you have a graphic card/chip and driver.
