/**
 * Present capabilities from other physical devices.
 * 
 * Description
 * 
 * {@code modes} always has {@link KHXDeviceGroup#VK_DEVICE_GROUP_PRESENT_MODE_LOCAL_BIT_KHX DEVICE_GROUP_PRESENT_MODE_LOCAL_BIT_KHX} set.
 * 
 * The present mode flags are also used when presenting an image, in {@link VkDeviceGroupPresentInfoKHX}{@code ::mode}.
 * 
 * If a device group only includes a single physical device, then {@code modes} must equal {@link KHXDeviceGroup#VK_DEVICE_GROUP_PRESENT_MODE_LOCAL_BIT_KHX DEVICE_GROUP_PRESENT_MODE_LOCAL_BIT_KHX}.
 * 
 * Valid Usage (Implicit)
 * 
 * 
 * {@code sType} must be {@link KHXDeviceGroup#VK_STRUCTURE_TYPE_DEVICE_GROUP_PRESENT_CAPABILITIES_KHX STRUCTURE_TYPE_DEVICE_GROUP_PRESENT_CAPABILITIES_KHX}
 * {@code pNext} must be {@code NULL}
 * 
 * 
 * See Also
 * 
 * {@link KHXDeviceGroup#vkGetDeviceGroupPresentCapabilitiesKHX GetDeviceGroupPresentCapabilitiesKHX}
 * 
 * Member documentation
 * 
 * 
 * {@code sType} – the type of this structure.
 * {@code pNext} – {@code NULL} or a pointer to an extension-specific structure.
 * {@code presentMask} – an array of masks, where the mask at element i is non-zero if physical device i has a presentation engine, and where bit j is set in element i if physical device i can present swapchain images from physical device j. If element i is non-zero, then bit i must be set.
 * {@code modes} – a bitmask of {@code VkDeviceGroupPresentModeFlagBitsKHX} indicating which device group presentation modes are supported.
 * 
 * 
 * Layout
 * 
 *  * struct VkDeviceGroupPresentCapabilitiesKHX {
 *     VkStructureType sType;
 *     const void * pNext;
 *     uint32_t presentMask[VK_MAX_DEVICE_GROUP_SIZE_KHX];
 *     VkDeviceGroupPresentModeFlagsKHX modes;
