Since bug 527047 there is the capability to change the scale level from nominal to max when exporting diagram as image. The goal is to increase the quality of the exported image.

But there is a problem with edit part using SVG image. The SVG quality is not improved. This is visible on the joined images.

* ScreenshotWith100Percent.png: SVG image rendered with a zoom of 100%
* ScreenshotWith400Percent.png: SVG image rendered with a zoom of 400%. The quality is OK
* exportWithNominalScaling.png: Export of a diagram, containing edit parts using SVG image, using nominal scale. The global quality is poor.
* exportWithMaxScaling.png: Export of a diagram containing edit parts using SVG image, using max scale. The global quality is improved (visible on edges and label). But the SVG image a the same quality as nominal scaling.

Steps to reproduce:
* Import project Bug527717 from Bug527717Project.zip in your workspace
* Open the diagram "new Diagram"
* Export this diagram as image with nominal scale.
* Export this diagram as image with max scale.
* Compare the quality of the tiger: It is the same. It should not.
