     11:    PetscDrawOpenX - Opens an X-window for use with the PetscDraw routines.

     13:    Collective on MPI_Comm

     15:    Input Parameters:
     16: +  comm - the communicator that will share X-window
     17: .  display - the X display on which to open,or null for the local machine
     18: .  title - the title to put in the title bar,or null for no title
     19: .  x,y - the screen coordinates of the upper left corner of window
     20:           may use PETSC_DECIDE for these two arguments, then PETSc places the
     21:           window
     22: -  w, h - the screen width and height in pixels,  or PETSC_DRAW_HALF_SIZE, PETSC_DRAW_FULL_SIZE,
     23:           or PETSC_DRAW_THIRD_SIZE or PETSC_DRAW_QUARTER_SIZE

     25:    Output Parameters:
     26: .  draw - the drawing context.

     28:    Options Database Keys:
     29: +  -nox - Disables all x-windows output
     30: .  -display <name> - Sets name of machine for the X display
     31: .  -draw_pause <pause> - Sets time (in seconds) that the
     32:        program pauses after PetscDrawPause() has been called
     33:        (0 is default, -1 implies until user input).
     34: .  -draw_cmap <name> - Sets the colormap to use.
     35: .  -draw_cmap_reverse - Reverses the colormap.
     36: .  -draw_cmap_brighten - Brighten (0 < beta < 1) or darken (-1 < beta < 0) the colormap.
     37: .  -draw_x_shared_colormap - Causes PETSc to use a shared
     38:        colormap. By default PETSc creates a separate color
     39:        for its windows, you must put the mouse into the graphics
     40:        window to see  the correct colors. This options forces
     41:        PETSc to use the default colormap which will usually result
     42:        in bad contour plots.
     43: .  -draw_fast - Does not create colormap for countour plots.
     44: .  -draw_double_buffer - Uses double buffering for smooth animation.
     45: -  -geometry - Indicates location and size of window.

     49:    Note:
     50:    When finished with the drawing context, it should be destroyed
     51:    with PetscDrawDestroy().

     53:    Note for Fortran Programmers:
     54:    Whenever indicating null character data in a Fortran code,
     55:    PETSC_NULL_CHARACTER must be employed; using NULL is not
     56:    correct for character data!  Thus, PETSC_NULL_CHARACTER can be
     57:    used for the display and title input parameters.
