If Metal context and IOSurface are available, Skia painter will use Ganesh GPU backend on macOS, which is noticeably faster than the default CPU backend. Painting pipeline: 1. (WebContent) Allocate IOSurface for backing store 2. (WebContent) Allocate MTLTexture that wraps IOSurface 3. (WebContent) Paint into MTLTexture using Skia 4. (Browser) Wrap IOSurface into Gfx::Painter and use QPainter/CoreGraphics to blit backing store into viewport. Things we should improve in the future: 1. Upload textures for images in advance instead of doing that before every repaint. 2. Teach AppKit client to read directly from IOSurface instead of copying.
