* This variable can be set to the following values:
* "0" - The window frame is not interactive when the cursor is hidden (no move, resize, etc)
* "1" - The window frame is interactive when the cursor is hidden
*
* By default SDL will allow interaction with the window frame when the cursor is hidden
