//////////////////////////////////////////////////////////////////////////
//	Let's do a little explanation of the parent Dialog class, shall we?
//	The first parameter we pass it is an image to use for the dialog box.
//
//	This image has to have the property that its width and height be
//	divisible by 3. Why? For stretching/tiling, in case you want the
//	dialog box to be bigger than the actual image. The image can
//	be thought of as being divided into regions. The 4 corners
//	are drawn normally, and the remaining chunks (which comprise a third
//	of the image height or the image width) are tiled to allow for 
//	the stretching of the dialog box.
//
//	The image for the dialog button works the same way and must have
//	the same properties. Dialogs use a DialogButton class which is exactly
//	the same as a normal button class, except that they support tiling
//	the image if it is stretched larger than the original image is.
//
//	The third parameter is the ID to use for the dialog box. 
//
//	The fourth indicates if the dialog is modal. If it is, then only the
//	dialog box and any widget above it (like its buttons) will receive
//	keyboard and mouse input. This is just like in Windows when a file
//	dialog appears and you can't click on the window of the application
//	below it.
//
//	The fifth parameter is the header to use for the dialog box.
//
//	The sixth parameter is the text to display in the body of the dialog
//	box. You can use the newline (\n) character for line breaks.
//
//	The seventh parameter is optional, and is only used if the eigth
//	parameter is Dialog::BUTTONS_FOOTER. This is the text to display on
//	the footer (bottom) dialog button.
//
//	The eigth parameter indicates what type of buttons are to display.
//	You can use BUTTONS_YES_NO or BUTTONS_OK_CANCEL for the standard
//	"Yes", "No" or "OK", "Cancel" options, BUTTONS_NONE for no buttons,
//	or BUTTONS_FOOTER for a single button that runs along the bottom.
//	Of course, you can change the labels on any of the buttons if you
//	like.
//
//	The YES/OK/FOOTER buttons have a value of 2000 + the dialog's ID.
//	The NO/CANCEL buttons have a value of 3000 + the dialog's ID.
