2. display the mappaint dialog
3. add it to the toolbar

icons scale down to 16px in mappaint dialog and 24px in main toolbar if they are to big

What happens instead?

Please provide any additional information below. Attach a screenshot if possible.

This is mainly problematic for svg as they often have higher default sizes.
