commit 70c0592a97c7dc9db0576d32b3bdbe4766520509

Resize composite overlay window when the root window changes.
- This allows some compositing managers to work, even after randr12 has changed the root window size.
- Thanks to ajax for figuring out the best place to put this.
- Example:
- xf86RandR12SetMode() calls EnableDisableFBAccess().
- That calls xf86SetRootClip() which in turn calls ResizeChildrenWinSize().
- The final step is the call to PositionWindow().
