min3d HUD about min3d HOT 4 OPEN

I've implemented a basic version of this by:

1. Adding a List<Object3d> _hudElements to Scene (with accessors)
2. Adding a drawHud() method to Renderer, which is called by onDrawFrame()

To add a HUD I then add elements to the hudElements array in my initScene code. 

See attached files for more detail. 

I will probably extend this to hook up onTouch so that it processes the 
elements in the hudElements array for taps and calls back onto the handler 
(i.e. a crude 3D widget set). I'll do this for my own usage. If you want me to 
contribute this back to the source tree let me know.  

Zonski, thanks very much for this. Apologies for the delay. 

Let me think about how I want to handle this -- either as a dedicated "HUD" 
like you've posted, or maybe an array of "scene layers", with options for 
perspective versus orthographic?

BTW, how are you going to/did you handle touch events on the 3D objects in your 
HUD?

This is a very important feature. Has it been decided upon? Right now I see no 
way of drawing HUD, especially since the custom renderer interface isn't done 
yet.

The only non-intrusive way I can imagine is drawing a rectangle in front of the 
camera and displaying HUD yourself. Not nice at all...

Dear Zwolenski
