  Make Framebuffer size check ES2-only.
  
  This is an ES2-only incompleteness check. We also need to require
  matching dimensions in D3D11, but make this an implementation
  specific check. Also make all implementation specific errors
  'UNSUPPORTED' since that catches all "non-ES" framebuffer
  restrictions.
  
  Note that we can't be conformant here in D3D11 currently, since the
  spec only makes an exception for mismatching formats for UNSUPPORTED,
  not for size checks. However, we don't have an easy solution.
