D3D11: Enable dirty bits for Framebuffer11. This patch works using a notification scheme - whenever a Texture or Renderbuffer changes in such a way as to recreate its RenderTarget, we pass a signal to the Framebuffer to invalidate some internal state. Everything is entirely tracked in the Renderer11 layer, and the GL layer is left untouched. A RenderTarget11 now tracks points to which it is bound, and the Framebuffer11 is mostly responsible for managing those links. The three locations where we notify a Framebuffer when its bound RenderTargets might be dirty are: 1) RenderTarget11::~RenderTarget 2) EGLImageD3D::copyToLocalRendertarget 3) TextureStorage11_2D::useLevelZeroWorkaroundTexture This patch gives about a 10% score increase in the D3D11 draw call benchmark on my system.
