For some reason this line of code confused git cl format
in that it would generate different results depending on when
it was called:

"PFNEGLSTREAMCONSUMERGLTEXTUREEXTERNALATTRIBSNVPROC
   ANGLE_EGL_StreamConsumerGLTextureExternalAttribsNV;"

I wasn't able to root cause the bug. Instead I worked around
it by changing the signatures for this file.
