Hello Michael, Perhaps I am missing something here, but first I have trouble seeing what ANGLE should provide which we are currently lacking (in fact I am not quite sure what you feel is wrong with our current solution at all which cannot be fixed in place), and secondly it looks from its web page like a Windows-only library to run OpenGL ES on top of DirectX rather than a cross-platform one to translate DirectX into WebGL. I am not even quite clear either why you think we need such a library - are you considering Windows guests being displayed in a host web browser? And if so, do you think that ANGLE would be suitable for being embedded into a guest display driver?
