Vulkan-Headers Vulkan-Loader 1.3.273

[Bruce Dubbs]

New point version.

[Xi Ruoyao]

By the way, I think there is a mistake in Vulkan-Loader dependencies. I'm pretty sure lxml is not required (I can build Vulkan-Loader w/o lxml), and I cannot find a reference to lxml in the code.

[Bruce Dubbs]

When updating these packages, please fix the Title to capitalize Loader and Headers to match both the tarball name and the extracted directory.

I confirm listing lxml is a mistake.

Vulkan-Headers has just one commit, but it does update a lot of header files and adds some new functions. The commit was titled "Update for Vulkan-Docs 1.3.273"

Vulkan-Loader:

Specify which layer type is being searched in log 
   Makes it clear which layer type is being searched for in any given set of paths.
Support Clang with GNU interface on Windows 
   By using CMAKE_CXX_COMPILER_FRONTEND_VARIANT, CMake will now distinguish
   clang from clang-cl, allowing the correct command line argument formats
   to be used.

   Making tests work required fixing up windows_shim.cpp's usage of wcscpy
   since that was triggering deprecation warnings. A simple for loop was
   used instead.
Add simple timer of ICD preloading in live tests 
   Adds a simple executable that times how long vkEnumerateInstanceExtensionProperties
   takes over and over to see how well the ICD preloading functions.
Unload drivers which report 0 physical devices 
   The loader did not unload any ICD's which contained zero physical devices, which
   could cause premature exhaustion of memory in some circumstances, like 32 bit
   applications. While the policy of the loader has been to keep things open for
   the duration of the instance, these ICD's don't meaningfully participate in
   anything due to the lack of VkPhysicalDevices.

   This change adds a check after vkEnumeratePhysicalDevices where pPhysicalDevices
   is not NULL such that all loader_icd_terms which reported zero physical devices
   have its vkDestroyInstance called, and removed from the loader_instance's
   icd_term linked list.
Use memset to clear structs 
   Several places manually zero'd out each member of a struct. This makes it possible to
   forget to zero out members, especially as structs change over time. Using memset
   prevents that possibility.
Fix spelling mistakes in comments 
   These creep in over time, and make the codebase harder to understand due to spelling
   errors causing confusion when reading comments.
build: Update to header 1.3.273
