//The previous code creates a new graphics device. It’s not going to make a whole lot of
//sense to you right now, but don’t worry that much about it. Just know that it works, and
//that I’ll get to it in much more detail in Chapter 7.
//The next part of the code sets up the event handlers (which are delegates):
state.graphics.DeviceLost += new EventHandler(this.InvalidateDeviceObjects);
state.graphics.DeviceReset += new EventHandler(this.RestoreDeviceObjects);
state.graphics.Disposing += new EventHandler(this.DeleteDeviceObjects);
// state.graphics.DeviceResizing += new CancelEventHandler( this.EnvironmentResizing );

//The first three events handle whenever a device is lost (say, if the user switches to another
//window), the device is reset for any reason, or the device is disposed of. These first three
//events are solid events; when they happen, you have to handle them. No ifs, ands, or buts
//about it—the operating system is telling you something happened and your event handler
//has to take care of the situation.
//The final event handles when the graphics device is resized, which is a special kind of
//event because it can be cancelled. A cancelable event is an event that your program can
//decide to reject. For example, if the user says he’s going to resize your game window, your
//program will get the event, but you can tell the operating system, “Nope, it’s not gonna
//happen!” and the event won’t complete. This behavior is used mostly to prevent forms
//from closing before the user saves his data in windows applications.
//The final part of the code returns true for a successful initialization, or catches any
//DirectXExceptions that may have been thrown and returns false:
return(true);
