Some fixes on the rendering engine and it's almost the finalized version of the engine

Some updates and fixes on the engine:
1. The engine is now running by default on fullscreen, it's now able to fetch user's machine resolution and configure to fit this resolution to get a best looking of the interface and rendering area.

2. I have made changes on the editing word coordinator axes. It's now much elegant than before, which has got a cone head and thinner sticks, making it easy to select as well.

3. The first two editing ball will be shown to indicate that the user has successfully add the first two control points.
