Fixes: 27071678
It's semi-common for apps to not realize surfaceRedrawNeeded
is a callback they can (and should) be handling, so have it be
more tolerant in lifecycle handling.
Specifically allow a renderer to have not yet been set on
GLSurfaceView, even though it was supposed to have been set already.
Apps are overriding the other lifecycle methods that require this
(created, changed, an destroyed) but not noticing this method.
