nit: These buffers are not technically backed by EGLImages. EGLImages are just
used as a mechanism to share these buffers with the GL. Maybe "GPU memory
buffers that are shared with the GL using EGLImages require
TEXTURE_EXTERNAL_OES."

       return GL_TEXTURE_EXTERNAL_OES;
     case gfx::IO_SURFACE_BUFFER:
       // IOSurface backed images require GL_TEXTURE_RECTANGLE_ARB.
