This requires knock-on upgrades for glslang and spirv-tools. I have also made the validation layers easier to use: - library files identified by layer definitions now use absolute paths - the layer definition path is prepended to XDG_DATA_DIRS Previously, one would have to modify LD_LIBRARY_PATH or install the derivation in a known location for vulkan-loader to find relevant files. These changes make using validation layers in a nix-shell work automatically. Use XDG_DATA_DIRS environment variable rather than VK_LAYER_PATH
