+Upon compilation, glslc is invoked to compile each shader, and the result is placed within `zig-cache`. All shaders which are compiled using a particular `ShaderCompileStep` are imported in a single Zig file using `@embedFile`, and this file can be added to an executable as a module using `addModule`. To slightly improve compile times, shader compilation is cached; as long as a shader's source and its compile commands stay the same, the shader is not recompiled. The SPIR-V code for any particular shader is aligned to that of a 32-bit integer as follows, as required by vkCreateShaderModule:
