HARDCOPY /GEOMETRY

        HARDCOPY /GEOMETRY Sizex[Unitx] Sizey[Unity]

    The /GEOMETRY option allows to customize the size of the hardcopy.  This
    option is supported on the following devices:
    - PNG: units allowed are 'p' (pixels) and 'r' (aspect ratio). If absent,
      units default to pixels.
    - SVG

    Typical use cases are:
      HARDCOPY /GEOMETRY 800 560    ! 800x560 pixels
      HARDCOPY /GEOMETRY 800p 560p  ! 800x560 pixels
      HARDCOPY /GEOMETRY 800 0.5r   ! Twice less pixels in Y than X: 800x400 pix
      HARDCOPY /GEOMETRY 3r 100     ! 3 times more pixels in X than Y: 300x100 p
      HARDCOPY /GEOMETRY 1r 2r      ! Invalid: both dimensions defined as
                                    ! ratio of the other

    Without this option, the hardcopy size can be ruled through the  follow-
    ing SIC logicals, using the same syntax as above:
    - PNG_GEOMETRY
    - SVG_GEOMETRY

    If neither the option is used nor the SIC logical is set, then the hard-
    copy size is defined with internal default values (800x560 pixels).
