// We must make sure the std::string we pass as name is still valid memory until the program ends.
// Since Vulkan is a C-Style API, it only accepts const char* as pObjectName parameter.
// Naming objects with unformatted names like "g_hTemporaryCommandBuffer" is no problem because
// this string ends up in the read-only data section of the program. However, if we for example want to
// name every item in a dynamic array of items (swapchain images for example), we can only use a std::string,
// and we must make sure the object lifetime of that string does not end before it's read as pObjectName.
// Therefore, we store the strings as a static unordered_set here just to be sure.
// Do not use a std::vector because it would continue to grow, eventually running out of memory.
