I do not think this is working or will work the way I expect. First of all it
is running without errors but then not producing any output. Secondly I think
conceptually it is going to slice the base page into multiple slices, but I my
specifications may need to have overlapping cropping areas as well (please see
attachment). So I think if there could be a way to simply run a loop using the
earlier cropbox technique that would be what I need.
Something like below:

<<
/EndPage 

(loop 1 with x1, y1, w1, h1)
{
  exch pop 0 eq {
    [/CropBox [x1 y1 w1 h1] /PAGE pdfmark
    true
  } {
    false
  } ifelse
}

(loop 2 with x2, y2, w2, h2)
{
  exch pop 0 eq {
    [/CropBox [x2 y2 w2 h2] /PAGE pdfmark
    true
  } {
    false
  } ifelse
}

>> setpagedevice

and so on. So with a single call to gswin32c, the loop will run 4 times for my
4 set of coordinates. Does this makes sense?
