Log Message:
-----------
BGE VBO updates:
- Changing Normal VBO from GL_STATIC_DRAW to GL_DYNAMIC_DRAW
- Replacing glBufferSubDataARB() with ZERO offset to glBufferDataARB() (they
work the same, and the latest is clear in its functionality).
- Removing unnecessary calls of: glBindBufferARB(GL_ARRAY_BUFFER_ARB, 0);
[Benoit, can you check if this last one is ok?]
