  Support EGL_(WIDTH|HEIGHT) in eglSurfaceAttrib(), fixed resize
  
  Setting EGL_WIDTH or EGL_HEIGHT results in mFixedWidth and mFixedHeight
  changing their values.
  
  Whenever the swap chain is tested for needing a resize, surfaces with
  mFixedSize are treated as if they should be resized to mFixedWidth and
  mFixedHeight from their current size. This way fixed-size surfaces
  can be resized - it's enough to do a couple of eglSurfaceAttrib() calls
  and then either let ANGLE check surface for needing a resize in due course,
  or force that by calling eglWaitNative().
