public abstract class BoundsManager
extends Object

BoundsManager is an acceleration structure for device-space related pixel bounds queries. The BoundsManager tracks a single ordinal value per bounds: the CompressedPaintersOrder of a draw The CompressedPaintersOrder enforces a specific submission order of draws to the GPU but can re-arrange draws out of their original painter's order if the GREATER depth test and the draw's Z value resolve out-of-order rendering.

It supports querying the most recent draw intersecting a bounding rect (represented as a CompressedPaintersOrder value), and recording a (bounds, CompressedPaintersOrder) pair.
