iOS: Disable worker contexts, and use sized formats Kimmo Kinnunen made this change downstream in WebKit. https://bugs.webkit.org/show_bug.cgi?id=215908 Disable ANGLE workers until EAGL implementation is more complete. Current implementation fails to compile any shader, since the compilation happens in the worker thread and worker EAGL context which does not use the same sharegroup as the main context. The shader objects are created in the main context but the shader source setting and compilation happens in the worker context. EAGL needs a flush between state changes, and adding that correctly is a bigger change to be done later. Use sized formats when calling [EAGLContext -texImageIOSurface] from EGL_ANGLE_iosurface_client_buffer code. The texImageIOSurface accepts parameters with glTexImage2D logic. On ES3, some of the internal formats must be sized formats. The EAGLContext instantiated by ANGLE is ES3, even if the ANGLE context would be ES2. No tests added since this should be caught with the many video related tests. It's unclear why this is not the case -- at least on real hw. This is to be investigated later, too.
