Vitrail Shaders

Changed

• On a backend other than Vulkan, nothing of the pack is drawn any more. The pack is still read and still shown in its settings screen, so it can be picked and configured ahead of the restart, but the game keeps its own image: the passes used to run there and draw a picture that was credible and wrong. A chat line the first time a world is shown says so and names the setting to change, Graphics API to "Prefer Vulkan (Experimental)" under Video Settings, beside the error the log already carried.

Fixed

• Body Camera's film grain moves again. The 0.7.3 hash rewrite took the frame time out of the grain, which writes it into the second argument of the idiom, and left a pattern stuck to the screen. The rewrite now only fires on a constant second argument; BSL's waving is untouched.

• No more dark oval under a mob when the pack draws its own shadows. The game's flat entity shadow was still drawn, lit as a translucent entity, under every mob the pack was already shading with its shadow map. It now goes away for as long as the pack has a map, which is what Iris does, and stays under a pack without one. The defect only showed with Entity Shadows on in the video settings.
