yeah, that seems to be coming from libepoxy..
I think at this point I blame a combination of libglvnd and libepoxy..
seems like libepoxy is calling
eglQueryContext(EGL_CONTEXT_CLIENT_TYPE) to figure out the current
API, but somehow that doesn't get through to mesa so the return ends
up being EGL_NONE. This happen's from run.c's glCreateProgram() call,
but somehow a previous eglQueryContext(EGL_CONTEXT_CLIENT_TYPE) when
run switched context before calling glCreateProgram() worked ok!?!
Sigh..
