/**
 * Image base header for a swapchain image.
 * 
 * Description
 * 
 * The {@link XrSwapchainImageBaseHeader} is a base structure that is extended by graphics API-specific stext:XrSwapchainImage* child structures.
 * 
 * Valid Usage (Implicit)
 * 
 * 
 * {@code type} must be one of the following XrStructureType values: {@link KHROpenGLEnable#XR_TYPE_SWAPCHAIN_IMAGE_OPENGL_KHR TYPE_SWAPCHAIN_IMAGE_OPENGL_KHR}, {@link KHRVulkanEnable#XR_TYPE_SWAPCHAIN_IMAGE_VULKAN_KHR TYPE_SWAPCHAIN_IMAGE_VULKAN_KHR}
 * {@code next} must be {@code NULL} or a valid pointer to the next structure in a structure chain
 * 
 * 
 * See Also
 * 
 * {@link METAEnvironmentDepth#xrEnumerateEnvironmentDepthSwapchainImagesMETA EnumerateEnvironmentDepthSwapchainImagesMETA}, {@link XR10#xrEnumerateSwapchainImages EnumerateSwapchainImages}
 * 
 * Layout
 * 
 * 
 * struct XrSwapchainImageBaseHeader {
 *     XrStructureType {@link #type};
 *     void * {@link #next};
 * }
