FWIW, The case that is currently crashing is when calling drawRect with an
bitmap shader that references an abandoned texture-backed SkImage.

Ok, they both wind up in the refTexureSafeForParams().  I really want to revisit
the abandoning of individual textures. It is the only case where we abandon
resources without abandoning the whole GrContext and I think it is going to be
hard to patch all the wholes. In general our safeguard around abandonment is to
check when we enter a high level function whether the context is abandoned and
if so we bail. The system is really designed for a mix of abandoned an valid
resources.
