SDL2: fix size of letterbox sequences

Browse source 
andrew-strong reported that using SDL2, with the window set to full
screen, but a windowed size less than full screen, caused letterbox
sequences, such as the player ship destroyed sequence, to render in a
subwindow sized to the dimensions game would have when unmaximized, even
if the game window is maximized at the time of the sequence.

tycho suggested a change that resolves this issue, and basic testing
showed no unwanted side effects.
