/* All this extension-dependent dispatch has to be stored per physical
device, not just on instance, because it's actually instance-level
functionality depending on a version of a particular device. According
to https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/chap3.html#fundamentals-validusage-versions :
Physical-device-level functionality or behavior added by a new core
version of the API must not be used unless it is supported by the
physical device as determined by VkPhysicalDeviceProperties::apiVersion
and the specified version of VkApplicationInfo::apiVersion.
and https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/chap4.html#_extending_physical_device_core_functionality :
New core physical-device-level functionality can be used when the
physical-device version is greater than or equal to the version of
Vulkan that added the new functionality. The Vulkan version supported
by a physical device can be obtained by calling
vkGetPhysicalDeviceProperties.
and https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/chap4.html#initialization-phys-dev-extensions :
Applications must not use a VkPhysicalDevice in any command added by an
extension or core version that is not supported by that physical
device.
Which means for example, if Vulkan 1.1 is supported by the instance, it
doesn't actually imply I can use vkGetPhysicalDeviceProperties2() -- I
can only use that in case the device supports 1.1 as well, which means I
have to call vkGetPhysicalDeviceProperties() first in order to be able
to call vkGetPhysicalDeviceProperties2().
On the other hand, if the device is 1.0 but the instance
supports VK_KHR_get_physical_device_properties2, I can call
vkGetPhysicalDeviceProperties2KHR() directly -- https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/chap4.html#initialization-phys-dev-extensions :
When the VK_KHR_get_physical_device_properties2 extension is enabled,
or when both the instance and the physical-device versions are at least
1.1, physical-device-level functionality of a device extension can be
used with a physical device if the corresponding extension is
enumerated by vkEnumerateDeviceExtensionProperties for that physical
device, even before a logical device has been created.
This also explains why e.g. VK_KHR_driver_properties is a device
extension and not instance extension -- I can only add it to the pNext
chain if the device is able to understand it, even though it's shoveled
there by an instance-level API. */
