Bug 2801 [Dialogs] DCR: ErrorDialog should not always show the error icon (1GJU7TK)
The class org.eclipse.jface.dialogs.ErrorDialog is used to display errors contained in an IStatus. The problem with the dialog is that it shows an error icon (red/cross) even though IStatus only has warnings or infos. The dialog would be more usable if the icon would correspond to the severity of IStatus and/or the dialog would offer to specify the image type (error, warning, info). NOTES:
bundles/org.eclipse.ui.workbench/extensions/org/eclipse/jface/dialogs/ErrorDialog.java
* (element type: <code>IStatus</code>).

	private java.util.List statusList;
/**
 * Creates an error dialog.
 * Note that the dialog will have no visual representation (no widgets)

 * <p>
 * Normally one should use <code>openError</code> to create and open one of these.
 * This constructor is useful only if the error object being displayed contains child
 * items <it>and</it> you need to specify a mask which will be used to filter the
 * displaying of these children.

 * @param parentShell the shell under which to create this dialog
