- Uses the InstanceCullingLoadBalancer to pre-distribute the work on the CPU to ensure even load.
- Make instance culling use the instance data offset in MDC instead of translating primitive IDs.
- Track single-instance draws separately from instanced to optimize handling (disable culling for single-instance primitives).

- Intermediate step towards making renderer instance-first.
- Enables simplification of instance culling setup.

- provides easier iteration on related code, plus sets the stage for abstraction for desktop/mobile version.

- Enables overlapping batched and non-batched instance culling (needed for batching work).
- Removes some explicit transitions & minor cleanup.
- Added tracking the required number of instances (fixes non-nanite VSM for large ISMs)

This avoids a long stall on mesh draw command recording tasks at the end of the frame and saves about .1 ms of work off the render thread.

- added explicit stereo mode to instance culling context.
- fixed the stencil setup pass parameter to include the InstancedView (lost in RDG conversion probably)
- restored the hack to run the stereo stencil pass twice (needed to make FSimpleMeshDrawCommandPass support setting up stereo)

- added a path to propagate and cache whether material modifies position (WPO) to enable invalidating cached pages (touches whole mesh command pipeline).
- added pixel shader verision of page copying & clearing.
- also added flag for whether cached the mesh draw command supports primitive id (which enables checing this earlier).

- dynamic primitive collectors now auto-commit when uploading dynamic primitives, simplifying use.
- fixed shadow stencil passes to properly use GPU-Scene instance culling (and instancing), now using FSimpleMeshDrawCommandPass
- Also move translucency shadow rendering to FSimpleMeshDrawCommandPass

- Added dynamic switches in addition to the ifdef.
- Added ifdef to disable workaround for legacy primitives for cube shadow when not used (enabled with GPU-Scene)
- Fixed some references to PrimitiveId in hair strand shaders

- LocalVertexFactory can fetch instance data from GPU-Scene
- regular Shadow map rendering can use instance culling view index (route to cube face)
- HISM/ISM/SM registers instance data
- Support for overriding mesh draw commands with indirect dispatch
