Volker Ruppert a4bbb76005 Partial rewrite of the client screen update code (should fix SF bug #1383). 
- moved code that sends the framebuffer update to the flush() method.
- method clear_screen() now sets up an update region to work as expected.
- fixed and improved function rfbAddUpdateRegion().
- added new function rfbSetUpdateRegion() to simplify code.
