Screenshot of PNG export options dialog

The issue is for image export options dialog. It is available using the following procedure:

1. In any document, choose File->Export, and choose PNG (or JPEG, or WebP).
2. Relevant "<Graphic format> Options" dialog opens, which has two control groups at the top inside "Size" section, connected with radio buttons: "Modify dimensions" and "Modify resolution".

The UI is confusing: the radio buttons create impression that you may change *either* one, *or* the other, but not both - but that is not the case: you may, for instance, first change dimensions, then activate the other radio button and change resolution, and the resulting image would use *both* changed values.

The radio buttons should be removed, and only labels should stay. Both groups of controls should be active at all times.
