I've searched my previous patches and I think that I've copied it during my 
first tries from dsurface.c: AttachmentTest. I don't know if it is needed in my 
tests too, probably not for the testbot. It looked like a good idea to have 
the check too if it had been in AttachmentTest already.

I can remove it with further patch (also from the dsurface.c: 
BackBufferAttachmentFlipTest). Should I remove it? I will wait for the patch to 
be applied first and I will send small correction to remove the broken() check, 
right? I can remove the broken() check from my "New attachment tests for 3D 
back buffers." patch too.

Should I remove it or keep it?
