/**
* <p>A dialog is a form that occupies a part of the screen and appears as a modal
* entity to the developer. Dialogs allow us to prompt users for information and
* rely on the information being available on the next line after the show method.</p>
* <p>Modality indicates that a dialog will block the calling thread even if the
* calling thread is the EDT. Notice that a dialog will not release the block
* until dispose is called even if show() from another form is called! Events are still performed thanks
* to the {@link com.codename1.ui.Display#invokeAndBlock(java.lang.Runnable)} capability of the
* <code>Display</code> class.</p>
* <p>To determine the size of the dialog use the show method that accepts 4 integer
* values, notice that these values accept margin from the four sides rather than x, y, width
* and height values!</p>
* <p>It's important to style a <code>Dialog</code> using {@link Dialog#getDialogStyle()} or
* {@link Dialog#setDialogUIID(java.lang.String)} methods rather than styling the dialog object directly.</p>
* <p>
* The <code>Dialog</code> class also includes support for popup dialog which is a dialog type that is positioned
* next to a component or screen area and points an arrow at that location.
* </p>
*
* <p>Typical dialog usage looks like this:</p>
* <script src="https://gist.github.com/codenameone/bbf5378aec028230ce93.js"></script>
*
* <p>See this sample for showing a dialog at the bottom of the screen:</p>
* <script src="https://gist.github.com/codenameone/60ca2cc54eea0cb12ede.js"></script>
