In multimonitor setup, only displays on primary monitor

[dperelman]

Thanks for the port to SDL2. I was very confused by the old version suddenly breaking after running upgrades.

I have a multi-monitor set-up and this version only displays on the primary monitor. I added some debugging statements so I can see Xscreensaver is still running an instance for each of my monitors, but it's only visible on the primary monitor. If I comment out the line calling SDL_SetWindowFullscreen(), then it does show the clock on every monitor... except at the wrong size: it's small in the bottom-left corner on my secondary monitor and it changes my primary monitor resolution to 640x480.

Playing around, I accidentally fixed this issue by adding the line

SDL_SetWindowPosition(window, window_x, window_y);

where above with the logic that gets the width and height, I added:

window_x = windowAttributes.x;
window_y = windowAttributes.y;

Not sure if there's a cleaner way to handle this or why moving the window to the position it was already in did anything.
