Steps to reproduce:
* Import project TitleBlockReproductionCaseLikeCapella from TitleBlockReproductionCaseLikeCapella.zip
* Open diagram "new DiagramLikeCapella"
* Create a "Title block" by doing a "drag'n'drop click" (from {100;100} to {500;400} for example.
--> KO : The "cells" have their default size, 100x50 defined in VSM. They must fill all the space of the container.

The behavior seems random, even after fix done for bug 577676 and bug 576305.

Technical information: 
In the first steps of the creation, the size of the drawn rectangle is set in GMF constraint of the "title block container" in method org.eclipse.sirius.diagram.ui.internal.refresh.AbstractCanonicalSynchronizer.updateDDiagramChildBounds(View, View) by getting size stored in SiriusLayoutDataManager during creation.
And then the method org.eclipse.sirius.diagram.ui.internal.refresh.diagram.DDiagramCanonicalSynchronizer.manageRegions() is called. Maybe this method is a good starting point.

To see next year...
