Flat light and back face cull worker mode

Add support for per face lighting and back face culling in worker mode. For larger models, this can offload a lot of calculations to another thread. Typical systems have 4-8 cores / threads to distribute work to.

Worker back face culling is a new property per object. Only works in worker mode (it would probably be a net loss if done on main thread.) This will potentially help some with GPU performance, when lighting is enabled.

nice work. i found that updating lights or baking lights does not work with worker mode. and turning on worker mode for something like a low poly cube in your 3dflatlight example, the bottom or the top parts of the cube, some rows stay black, not a big deal tho. looking forward to finally add lights to my game.

Thanks for the feedback - I'll take a look at making update light / baking work in worker mode.

For the cube, if you also have Worker Back Face Cull enabled, that requires the vertices of the 3D Model to be ordered consistently and properly (CW / CCW). It may be the case that they are not organized that way in your model. You could try an import and export of blender to see if that helps fix the ordering.
