This function returns whether the Vulkan loader and any minimally functional ICD have been found.
The availability of a Vulkan loader and even an ICD does not by itself guarantee that surface creation or even instance creation is possible. Call glfwGetRequiredInstanceExtensions to check whether the extensions necessary for Vulkan surface creation are available and glfwGetPhysicalDevicePresentationSupport to check whether a queue family of a physical device supports image presentation.
Returns number
GLFW_TRUE if Vulkan is minimally available, or GLFW_FALSE otherwise.
