Description:
When I export a Calc sheet as a PNG image, the default resolution is 119 pixels/inch. If I increase it to 300 pixels/inch, I get exactly the same PNG image.



Steps to Reproduce:
1. I click on "File" > "Export".
2. I Select "PNG".
3. I enable "Selection".
4. I click on "Save".
5. I click on "Modify Resolution" and I type a value.
6. I click on "OK".

Actual Results:
The exported PNG image remains the same regardless the resolution you've set.

Expected Results:
The exported PNG image should reflect the change of resolution.


Reproducible: Always


User Profile Reset: No

Additional Info:
As a separate note, it would be awesome if a sheet could be exported as an SVG document (you can do this already with a chart), but I presume it must something difficult to do and probably not very much demanded by users.
