@brief Send GetProperty request to get _NET_SUPPORTED root window
property
_NET_SUPPORTED, ATOM[]/32
This property MUST be set by the Window Manager to indicate which
hints it supports. For example: considering _NET_WM_STATE both this
atom and all supported states e.g. _NET_WM_STATE_MODAL,
_NET_WM_STATE_STICKY, would be listed. This assumes that backwards
incompatible changes will not be made to the hints (without being
renamed).
This form can be used only if the request will cause a reply to be
generated. Any returned error will be placed in the event queue.
@param ewmh The information relative to EWMH
@param screen_nbr The screen number
@return The _NET_SUPPORTED cookie of the GetProperty request
