Build the LOD pyramid up to targetLevel if it isn't already cached.
Each level halves dims via 2×2 mean-pooling of the parent (NaN-skip). Idempotent — repeated calls with smaller targetLevel are no-ops.
Stops early if a level would shrink below 32×32 (further pooling is useless detail-wise) or if memory allocation throws.

Source-grid tile fetcher (kept for Stage A/B compat tests).
Reads a sub-rectangle rows [r0, r0+h) × cols [c0, c0+w) from zQuantized, mean-pools by lod×lod, writes row-major uint8 indices to out. Stage C uses getFigureDisplayTile instead — that one resamples to display-pixel grid in one pass.

Display-grid tile resampler.
Fills a displayH × displayW row-major uint8 buffer with mean-pooled samples from the dataset's zQuantized, applying optional log10 inverse on either axis so the buffer can be blitted directly to the panel's pixel grid.
srcR0, srcC0, srcH, srcW : visible source-rect in source-cell coords (fractional allowed for log inverse) xLog, yLog : log10 axis transforms — when set, the source-cell at display-pixel u (or v) is srcC0 * (srcC1/srcC0)^(u/displayW), etc. Requires srcC0 > 0 (yLog: srcR0 > 0). out : caller-allocated, size ≥ displayH*displayW
Per display pixel:
- compute its source-cell centre via linear or log map
- mean-pool over a small ⌈srcStep⌉×⌈cStep⌉ block centred there
- skip NaN sentinels (idx 255), write 255 if the block is all-NaN
Cost: O(displayH * displayW * ⌈rStep⌉ * ⌈cStep⌉) — for a 800×600 panel showing the full 10000² extent that's ~30M ops, ~30ms in WASM. The upcoming Stage D LOD pyramid drops this to ~3 ms by reading from a pre-pooled level rather than the L0 source.
Returns false if request is out of range / not imagesc / no zQuantized / log requested with non-positive source coords.
