class FrameGraph

The frame tree, plus a one-tick pose cache.

Resolution walks to the root and composes, which is O(depth) — depth is 4-6 in practice. The cache exists because a tick resolves the same handful of frames for every entity in them, and evaluate for an orbital frame runs a Kepler solve.
