This avoid putting too much work in only one thread for building very long surfel lists.
Instead of insertion sort, we use a prefix sum where all surfel scan the whole ray
list to know their position. Only the coplanar surfel patching is dispatched as
one thread per list.
This is currently a bruteforce approach and could be optimized further.
On top of this, we add a heuristic to scale the amount of work from the baking
depending on the scene complexity. Complex scene will have more overhead but
will remain responsive during baking, while simple scene will be faster to bake.
This avoids hitting TDR in most cases.
The update refresh is now limited to 1 per second to avoid the readback overhead.
