People asked for 120 FPS, so this adds an option to set 120 FPS. I also added an option to turn VSync on or off, plus an option for sleeping between frames. Some people reported they weren't getting 60 FPS, so this might have been the cause. The app spends more time waiting for the next frame then it does rendering it, so making the app sleep prevents needless CPU usage while it waits. Perhaps it liked to "sleep in" sometimes. ːsteammockingː

Fixed how the waste pile spreads out in Duchess of Luynes after undo or redo.
Fixed the limited redeal in Little Windmill so that you can actually play the flipped card.

PS: You can press control-P to toggle seeing the current FPS you are getting in the top-left corner.
