Bug#1064335: mutter-common: xwayland apps ignore scaling settings

[Austin Pringle]

This bug also appears to break window titles and window decorations 
under xwayland as well; now, server-side window controls no longer 
respect user preference for positioning, ie,  they always render on the 
left of the titlebar, even if the user has preferences set for them to 
be on the right, and it always draws minimize, maximize, and close, even 
if the user preferences only want the "close" button to be drawn.
