Dion Moult 102ac551b3 Add VisibilityState/SelectionState tests; test real quantization helpers ...

test_instanced_geometry previously re-implemented vertex quantization
inline, with a stale comment claiming the helpers still lived in
ViewportWindow.cpp. They now live in VertexQuantization.h, so route the
test through the real quantizeVertex/octEncodeNormal and add coverage
for the degenerate-axis path, octahedral normal round-trip, the i8
normal error bound (~0.78 deg worst observed), and color passthrough.

Add test_visibility and test_selection: Tier-1 coverage of the two
per-object viewport state machines. Both are QObjects for their
changed() signal but touch no GL on the construction/mutation path, so
the tests exercise the pure CPU logic without a context.

Suite goes from 39 to 61 cases.
