Description:
When a document contains images that are flipped (horizontally or vertically) and I print the document in "two pages per sheet"-mode, they are not flipped on the printed output. 

Steps to Reproduce:
1. Create a new Draw document.
2. Click "Insert --> Image..." and choose a random image.
3. Flip the image (doesn't matter if vertically or horizontally)
4. Click "File --> Print", select "Print fo file" (no actual printing is necessary to expose the bug)
5. Go to "Page Layout"
6. Select "Pages per sheet: 2"
7. Go back to "General", click "Print to file..."
8. Open the generated PDF document.

Actual Results:  
The image that was flipped in Draw is not flipped in the print/exported file.

Expected Results:
Of course the image should be also flipped on the print.


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

Additional Info:
This does _not_ happen when printing is done with "pages per sheet:1".

I have tested the Flatpak version of LO 6.0.1.1 on Ubuntu 17.10, and also LO 5.4.4.2 which is included in Ubuntu 17.10. Both versions contain the bug.
