Dear Maintainer,

poppler 26.06 changed the Page box accessors (getMediaBox(), getCropBox()
and friends) to return a const reference instead of a pointer, in upstream
commit d50a4510 "Some const PDFRectangle * to const PDFRectangle &"

pdftoipe still assigns the result to a pointer, so it will FTBFS once
poppler >= 26.06 reaches unstable:

```
xmloutputdev.cpp:68:48: error: cannot convert 'const PDFRectangle' to 'const PDFRectangle*' in initialization
xmloutputdev.cpp:69:46: error: cannot convert 'const PDFRectangle' to 'const PDFRectangle*' in initialization
```

This was found in a test rebuild against poppler 26.07.0. Unstable is still
at 26.01.0-5, so the package builds fine today.

The attached patch takes the address of the returned reference, guarded with
the POPPLER_VERSION_AT_LEAST macro pdftoipe already defines and uses for
poppler. It is a no-op with the current poppler in unstable, so it can be 
applied now, ahead of the transition

Description: Fix FTBFS with poppler >= 26.06
 poppler 26.06 changed the Page box accessors to return a const
 reference instead of a pointer. Take the address of the result,
 guarded by a version check so older poppler still builds
