// works great *except* you don't get focus visuals for any of the controls.
//
// So to get around that, we don't mess with the template of the window itself, but instead:
// 1) Programmatically create a ContentPresenter and set it as the content of the Window (dialog)
// 2) Change the default content property to be "MainContent" (so the xaml for DialogBase derivations looks "normal")
// 3) Bind the content presenter to the MainContent property (and the template to MainContentTemplate)
//
// Viola! Plus the dialogs are now individually customizable via MainContentTemplate.
