Apple releases C++ wrapper for Metal.

Metal-cpp is a low-overhead C++ interface for Metal that helps developers add Metal functionality to graphics apps, games, and game engines that are written in C++.

Highlights:

• Drop in C++ alternative interface to the Metal Objective-C headers.
• Direct mapping of all Metal Objective-C classes, constants and enums to C++ in the MTL C++ namespace.
• No measurable overhead compared to calling Metal Objective-C headers, due to inlining of C++ function calls.
• No usage of wrapper containers that require additional allocations.
• Identical header files and function/constant/enum availability for iOS, iPadOS, macOS and tvOS.
• Backwards compatibility: All bool MTL::Device::supports...() functions check if their required selectors exist and automatically return false if not.
• String (ErrorDomain) constants are weak linked and automatically set to nullptr if not available.

Reports arise that Apple Watch Series 7 fails to render app icons for some apps. Issue might be related with icons being rendered in the wrong size. Also, some complications are rendered incorrectly.

Biggest problem here is that issue is NOT reproduced on Apple Watch Series 7 simulator.
