 * <span class="label label-info">Modified</span> The  @org.eclipse.sirius.diagram.ui.tools.api.part.DiagramEditPartService.DiagramEditPartService@ class which can be used to export diagrams as images is now automatically adapting the output resolution for raster image based on maximum buffer size specified through the @plugin.propeties@ file of the @org.eclipse.sirius.diagram.ui@ plugin. This leads to a noticeable increase of the export image size (you can expect a 10 factor on small diagrams) and the method will no longer fail with OutOfMemory errors as bigger diagrams will lead to a lower output resolution. Implementers using this class can override the @DiagramEditPartService.getMaximumTotalSize()@ method to return their own limit or @DiagramEditPartService.getExportResolutionFactor(DiagramEditPart, SiriusDiagramImageGenerator)@  and return @1.0@ to get back to the previous behavior.
