| comm | Communicator of participating processes | |
| display | Name of X window display.  If null, display will be taken from
the DISPLAY variable on the process with rank 0 in comm.  If that is
either undefined, or starts with w ":", then the value of display is
`hostname`:0 | |
| x,y | position of the window.  If (-1,-1), then the user should be
asked to position the window (this is a window manager issue). | |
| w,h | width and height of the window, in pixels. | |
| is_collective | true if the graphics operations are collective; this
allows the MPE graphics operations to make fewer connections to the 
display.  If false, then all processes in the communicator comm will 
open the display; this could exceed the number of connections that your
X window server allows.  Not yet implemented. |
