This replaces the old backend that exclusively used EGL windowing with one that can also use ANGLE's ability to render to directly to a texture. The advantage of this is that it allows mpv to create the swap chain itself and this allows mpv to use a flip-mode swap chain on a HWND (which avoids problems with DirectComposition) and to use a longer swap chain that has six backbuffers by default (which reportedly fixes problems with rendering 24fps video on 24Hz monitors.) Also, "screenshot window" should now work on DXGI 1.2 and up (Windows 8 and up.)
