This fixes the ripple bug reported by LG:
https://b.corp.google.com/issues/68964656
In that bug, the button is so tall that our image shader returns
a null fragment processor because the height exceeds GL_MAX_TEXTURE_SIZE.
If we return null paint, the ripple is completely gone. This CL returns
a default paint so we can still see the ripple, and that matches HWUI's
behaviour.
A GM will be added later after some other urgent Android ripple bug fixes.
