bug#41613: 26.1; ps-paper-type does not change page size

[Marvin Gülker]

Dear Maintainers,

setting the `ps-paper-type' variable and then calling 
`ps-print-buffer-with-faces' does not have an effect on the paper size 
of the page at all. It only affects the region in which the text drawn 
onto a standard-sized paper. For instance, if `ps-paper-size' is set to 
`diskette' (which is very small) the drawing area is confined to a very 
little region on the bottom-left of a full-size A4 paper sheet. I would 
have expected that setting `ps-paper-size' changes the actual paper 
size, not the drawing region, so that the resulting PS file has the 
dimensions of (in this example) `diskette'.

To reproduce, create a file with several paragraphs of arbitrary text so 
it does not fit on one page of the chosen size. Then, start Emacs with 
emacs -Q and do the following:

1. Visit said file.
2. M-x set-variable ps-paper-type diskette
3. M-x set-variable ps-print-header nil ;; without this an error occurs
4. C-u M-x ps-print-buffer-with-faces result.ps

Open the resulting PS file with ghostscript or convert it to PDF with 
ps2pdf. The text is drawn onto a very small region on the bottom-left of 
an A4 paper sheet. Instead, it should have been a very small page entirely.
