Remarks

An alternative to surfaceRedrawNeeded where it is not required to block until the redraw is complete. You should initiate the redraw, and return, later invoking drawingFinished when your redraw is complete.

This can be useful to avoid blocking your main application thread on rendering.

As of O, if this is implemented #surfaceRedrawNeeded will not be called. However it is still recommended to implement #surfaceRedrawNeeded for compatibility with older versions of the platform.
