I'd definitely like to use ANGLE everywhere, right now we're running into a particular error just with Windows XP users:
"The procedure entry point strnlen could not be located in the dynamic link library msvcrt.dll"
If I can crack that we'll probably switch to ANGLE everywhere on windows, once we've done the proper regression testing. For now this was an experiment to see if I could get a workaround good enough to ship some of my own stuff in the next week while we continue to improve the foundation long term.
