  - bindQuadVertexVBO
```
public static void bindQuadVertexVBO(int location)
```
    Bind VBO for a simple quad. Handy for simple custom RenderLayers Vertices: float[]{ -1, -1, -1, 1, 1, -1, 1, 1 }
    GL.drawArrays(GL20.TRIANGLE_STRIP, 0, 4);
  - bindQuadIndicesVBO
```
public static void bindQuadIndicesVBO()
```
    Bind indices for rendering up to MAX_QUADS (512), ie. MAX_INDICES (512*6) in one draw call. Vertex order is 0-1-2 2-1-3
  - animate
```
public static void animate()
```
    Trigger next redraw from GL-Thread. This should be used to animate LayerRenderers instead of calling Map.render().
