OverlayDrawer 2.7.0 API

```
public class OverlayDrawer

                    
```
Draws overlays through Overlay. - Provides a Canvas to be passed to the Overlay - Lets the overlay draw there: draw - Renders this into the current EGL window: render - Applies the Issue514Workaround the correct way In the future we might want to use a different approach than GlTextureDrawer, SurfaceTexture and GL_TEXTURE_EXTERNAL_OES, for example by using a regular GL_TEXTURE_2D that might be filled through glTexImage2D. The current approach has some issues, for example see Issue514Workaround.

- Method Detail
  - draw
```
 void draw(Overlay.Target target)
```
    Should be called to draw the Overlay on the given Overlay.Target.This will provide a working Canvas to the overlay and also update thedrawn contents to a GLES texture.
    
    Parameters:
    
    target - the target
  - getTransform
```
 Array<float> getTransform()
```
    Returns the transform that should be used to render the drawn content.This should be called after draw and can be modified.
  - render
```
 void render(long timestampUs)
```
    Renders the drawn content in the current EGL surface, assuming there is one.Should be called after draw and any getTransform modification.
    
    Parameters:
    
    timestampUs - frame timestamp
  - release
```
 void release()
```
    Releases resources.
