macOS: bundle and use MetalANGLE to enable Metal rendering This commit adjusts the window layer to have it try to load EGL implementations on macOS. This is important as the system provided OpenGL implementation is deprecated and I wanted to have a path forward for when it is finally removed. If EGL fails to initialize, we fall back to the CGL/OpenGL implementation that we used previously. I've included binaries built for 64-bit intel from the MetalANGLE project; here's how I built them: ``` git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git --depth 1 git clone https://github.com/kakashidinho/metalangle --depth 1 cd metalangle PATH=$PWD/../depot_tools:$PATH python scripts/bootstrap.py PATH=$PWD/../depot_tools:$PATH gclient sync PATH=$PWD/../depot_tools:$PATH gn --args="is_debug=false angle_enable_metal=true angle_enable_vulkan=false angle_enable_gl=false angle_build_all=false" gen out/Release PATH=$PWD/../depot_tools:$PATH autoninja -C out/Release ``` Those steps are a little too long to want to put them directly into the wezterm CI. It is important for metalangle to be >= https://github.com/kakashidinho/metalangle/commit/8230df39a500e1db62fdd68d2b1e767120747c39 in order for scaling to be handled correctly when dragging windows between monitors. refs: https://github.com/kakashidinho/metalangle/issues/34 2020-10-17 19:22:34 +03:00			`// Copyright 2018 The ANGLE Project Authors.`
