Instancing: skip the buckets of a cell lying wholly beyond the range of their instances (#225)

Browse Source 
* perf(instancing): skip a cell's buckets lying wholly beyond the range of their instances

* perf(instancing): go only through the instances drawn one by one in the per-node pass

* perf(instancing): leave out of the color pass the cells holding only instances too far to be drawn

* refactor(instancing): keep the caches of the instances of a cell without mutable fields, set by the renderer when the cell is queued
