* Split render/ into scene/ and session/. The scene/ folder now contains the scene and its nodes. The session/ folder contains the render session and associated data structures like drivers and render buffers. * Move top level kernel headers into new folders kernel/camera/, kernel/film/, kernel/light/, kernel/sample/, kernel/util/ * Move integrator related kernel headers into kernel/integrator/ * Move OSL shaders from kernel/shaders/ to kernel/osl/shaders/ For patches and branches, git merge and rebase should be able to detect the renames and move over code to the right file.
