When an edge is created with the snapToGrid enabled, it is sometimes not snaped to the grid. This is caused by a bug in NodeFigure where the getBounds() method is used to create the anchor and after, the getHandleBounds() is used to compute the corresponding location. The both methods do not return the same Rectangle. This explains the small shift that can be observed.

Steps to reproduce:
* Import the project "EdgeCreationPositionTest" (from "EdgeCreationPositionTest.zip")
* Open the diagram "Container"
* Activate the snapToGrid ("Ruler Units"=Pixels, and "Grid Spacing"=100)
* Activate the "Show Grid" option
* Enable the preference "Enable user specific default values" in Preferences/Sirius/Sirius Diagram/Connections" and set "Line style" to Rectilinear.
* Create an edge with the tool "Super" between "A" and "B" near the top grid line (y = 100).
* The edge is just above the grid line: KO it should be on the grid line.
