ui/cocoa: Cope with first surface being same as initial window size 

Do the recalculation of the content dimensions in switchSurface if the
current cdx is zero as well as if the new surface is a different size to
the current window. This catches the case where the first surface registered
happens to be 640x480 (our current window size), and fixes a bug where we
would always display a black screen until the first surface of a different
size was registered.
