Initialize lightShades so we don't get undefined behaviour when summing them, should still be mostly stubbed out by the compiler anyway if shadingmodel doesn't use it Delete all code, shaders and dependencies from other rendering pipelines Rewrite visualize_physics without deferred and deprecated stuff, also fix a bug with depth sorting Fix references to old pipelines on remainder of shaders Fix debug_sunshadow, update all_shaders list and delete compiled shaders for stuff we don't use anymore Remove HSL Grain and old Volumetrics from SFM, note that SFM lights already cast volumetrics in our pipeline without that Fix crash on moviedoc on maps with volumetrics Revert deletion of debug_sunshadow_vis.vmat Put RecoverWorldPosFromProjectedDepthAndRay on shared code
