/* The printer device units on win32 are 1 unit == 1 dot and the

* cordinate space to 1 unit is 1 point as expected by the

* the origin down so that the each test is drawn at the bottom
* left corner of the page. This is because the bottom left corner
* of the PNG image that ghostscript creates is positioned at
* origin of the PS coordinates (ie the bottom left of the page).
* The left and bottom margins are stored in win32_target_closure
* as size of the PNG image needs to be increased as the test
* output is offset from the bottom left by the non printable
* margins. After the PNG is created the margins will be chopped
* off so the image matches the reference image.
