	GPUSurfaceMetalDelegate (MTLRenderTargetType render_target)
	Construct a new GPUSurfaceMetalDelegate object with the specified render_target type. More...
virtual	~GPUSurfaceMetalDelegate ()
virtual GPUCAMetalLayerHandle	GetCAMetalLayer (const SkISize &frame_info) const =0
	Returns the handle to the CAMetalLayer to render to. This is only called when the specified render target type is kCAMetalLayer. More...
virtual bool	PresentDrawable (GrMTLHandle drawable) const =0
	Presents the drawable to the "screen". The drawable is obtained from the CAMetalLayer that given by GetCAMetalLayer call. This is only called when the specified render target type in kCAMetalLayer. More...
virtual GPUMTLTextureInfo	GetMTLTexture (const SkISize &frame_info) const =0
	Returns the handle to the MTLTexture to render to. This is only called when the specified render target type is kMTLTexture. More...
virtual bool	PresentTexture (GPUMTLTextureInfo texture) const =0
	Presents the texture with texture_id to the "screen". texture_id corresponds to a texture that has been obtained by an earlier call to GetMTLTexture. This is only called when the specified render target type is kMTLTexture. More...
virtual bool	AllowsDrawingWhenGpuDisabled () const
	Whether to allow drawing to the surface when the GPU is disabled. More...
