*--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.
*--xinerama-shadow-crop*::
Crop shadow of a window fully on a particular Xinerama screen to the screen.
*--crop-shadow-to-monitor*::
Crop shadow of a window fully on a particular monitor to that monitor. This is currently implemented using the X RandR extension.
*--backend* 'BACKEND'::
Specify the backend to use: `xrender`, `glx`, or `xr_glx_hybrid`. `xrender` is the default one.
