cc: Stop testing occlusion by making awkward queries.

cc: Stop testing occlusion by making awkward queries.

We used to test the state of the occlusion tracker by making queries
for various input rects to try and guess what its occlusion state
must be. This is bad. Instead, we can query the state directly.

This removes all state queries from tests that are verifying the
occlusion tracker's internal state changes correctly. And adds some
new tests that just set internal state and verify the query methods
work correctly.

A long-standing self-wish!

lgtm!!

The concept of checking the replica's occlusion was now only a concept in the
tests, the OcclusionTracker is agnostic about replica queries vs surface
queries, it just takes a transform. So I removed that parameter from the test
harness and removed the tests for it, which were only testing the harness after
all.
