Streaming Out-of-core Textures

Here is the other scene with a lot of (13600) unique meshes and 12GB textures. 6M unique triangles and 30M instanced. It’s interesting to test loading performance for the scene with so many small meshes.

Rendering Performance: 1600x900 image, 61M samples/second, 6 seconds to render 4 render iterations (256 path tracing samples per pixel).

Scene Builder Performance: one or two GPUs spend 1 second to launch the renderer (read geometry meshes from files and build ray tracing acceleration structures). The previous version took almost 10 seconds to load this scene.
