/* X11 based SDL video driver implementation. |

Note: This implementation does not currently need X11 thread locking, |
|
30 |
since the event thread uses a separate X connection and any |
|
31 |
additional locking necessary is handled internally. However, |
|
32 |
if full locking is neccessary, take a look at XInitThreads(). |
