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.
