 * This example demonstrates a bug with SDL2 and the Razer DeathAdder 2013
 * mouse on Linux. There might be other configurations where this bug occurs.
 *
 * Press and hold the middle mouse button. This shows a 'Chat wheel' dummy.
 * Move the mouse a bit while holding the middle mouse button.  After releasing
 * the middle mouse button, the cursor position should be restored to its
 * original position.
