Clip control on the Apple GPU
> Here’s a little secret: there are two graphics APIs called “Metal”. There’s the Metal you know, a limited API that Apple documents for App Store developers, an API that lacks useful features supported by OpenGL and Vulkan.<p>> And there’s the Metal that Apple uses themselves, an internal API adding back features that Apple doesn’t want you using.<p>Apple does stuff like this so much and gets so little flak for it.<p>I use macOS since it seems like the least bad option of you want a Unix but also don't want to spend a lot of time on system management, but this is a real turn-off.
