SkSurface factory methods have been moved to the SkSurfaces namespace. Many have been renamed to be more succinct or self-consistent. Factory methods specific to the Ganesh GPU backend are defined publicly in include/gpu/ganesh/SkSurfaceGanesh.h. The Metal Ganesh backend has some specific factories in include/gpu/ganesh/mtl/SkSurfaceMetal.h.

• SkSurface::MakeFromAHardwareBuffer -> SkSurfaces::WrapAndroidHardwareBuffer
• SkSurface::MakeFromBackendRenderTarget -> SkSurfaces::WrapBackendRenderTarget
• SkSurface::MakeFromBackendTexture -> SkSurfaces::WrapBackendTexture
• SkSurface::MakeFromCAMetalLayer -> SkSurfaces::WrapCAMetalLayer
• SkSurface::MakeFromMTKView -> SkSurfaces::WrapMTKView
• SkSurface::MakeGraphite -> SkSurfaces::RenderTarget
• SkSurface::MakeGraphiteFromBackendTexture -> SkSurfaces::WrapBackendTexture
• SkSurface::MakeNull -> SkSurfaces::Null
• SkSurface::MakeRaster -> SkSurfaces::Raster
• SkSurface::MakeRasterDirect -> SkSurfaces::WrapPixels
• SkSurface::MakeRasterDirectReleaseProc -> SkSurfaces::WrapPixels
• SkSurface::MakeRasterN32Premul -> SkSurfaces::Raster (clients should make SkImageInfo)
• SkSurface::MakeRenderTarget -> SkSurfaces::RenderTarget
