Merged requested to merge 283-enable-having-multiple-output-formats-for-raildiagrams into develop
- Generalize the image generation back-end, and make a second debug output target.
- Add tests, make fixes.
Tests work for the current graphics settings. Unfortunately, as soon as you change rendering settings everything dies again.
java.awt doesn't follow its own promises and doesn't give stable graphics output.
That is however for the next patch.
Closes #283 (closed)
