/* 

* This tutorial covers creating a mesh viewer.
*
* It is similar to the native tutorial, but different.
* Since much of the gui and xml stuff is not in the
* .NET wrapper yet, I decided to use winforms and
* the .NET xml mush for those portions of the tutorial.
*
* Some of this tutorial is based on the work Braneloc did
* on Tutorial 14.
*
* The tutorial also includes some other interesting stuff
* that I decided to play with.
*
* For instance, you can change the driver in the middle of
* looking at a mesh.
* Since I used .net 2.0 & VS2005, you can also move the
* toolbar around the form.  (A new freebe in .net 2.0)
*
* DISCLAIMERS:  This will not work with .net 1.1.
* The reason is that some of the controls I used in this
* tutorial are not available in .net 1.1.
* Most of the controls that I know have changed are the
* menu and toolbar stuff.
* The new stuff now has names like "MenuStrip",
* "ToolStrip", and "ToolStripMenuItem", etc.
* Seems kinda silly, I know, but I'm sure someone over
* in Redmond really thought they had a great idea.
*
* Also, MS changed their xml api in .net 2.0.
* The xml part of the tutorial might port to .net 1.1
* just fine, but I'm not sure and not ambitious enough
* to check it out myself.
*
* BUGS:  Yeah, I'm sure there's a few in there.
* I notice when switching drivers, the app will
* sometimes lock.  I haven't quite figured out why yet,
* but it seems to have something to do with Irrlicht
* having a null device.EventReceiver.  Also, the
* debugger will sometimes point to a problem with fonts
* in this case.
*
* The winforms event responses are very doggy.
* I tried a couple of Application.DoEvents() in the render loop,
* but they didn't seem to help much.  I may
* look at this in the future.
*
* FINAL NOTE:  If you happen to find any fixes for any of the
* bugs listed above or any new ones you find, share them with
* the community.  Post about them on the forum, and update
* the Wiki.
*
* Getting it working: 
* Create project as windows form, and add the 2 Irrlicht DLL's to it.
* (This file is the only one needed in the project)
* Add open.bmp and help.bmp from the Irrlicht media directory to the
* resources.
* You'll probably need to rebind the images to the toolstrip, hint,
* open is the one on the left..
