/*
* update_shadow
* Returns: 1 for success, 0 for failure
* Description: creates a libdecoration shadow context and updates
* the decoration context for the shadow for the properties that we
* have already read from the root window.
*
* For the pixmap mode we have opt_shadow which is passed to
* decor_shadow_create (which contains the shadow settings from
* the root window)
*
* For the reparenting mode we always enforce a zero-shadow in
* the opt_no_shadow passed to decor_shadow_create.
*
* We do something similar for the maximimzed mode as well
