* FSCREEN_CURRENT and FSCREEN_XYARG. For FSCREEN_CURRENT its mouse_ev member
* may be given. It is tried to find out the pointer position from the event
* first before querying the pointer. For FSCREEN_XYPOS the xpos member is used
* to fetch the x/y position of the point on the screen. If arg is NULL, the
* position 0 0 is assumed instead.
*
* Any of the arguments arg, x, y, w and h may be NULL.
*
* FSCREEN_GLOBAL: return the global screen dimensions
* FSCREEN_CURRENT: return dimensions of the screen with the pointer
* FSCREEN_PRIMARY: return the primary screen dimensions
* FSCREEN_XYPOS: return dimensions of the screen with the given coordinates
*
* The function returns False if the global screen was returned and more than
* one screen is configured. Otherwise it returns True.
