* Fix sending of certain keyboard input to terminal (fixes PageUp / PageDown / function 
keys etc.)
* Performance tweak - When updating the terminal window, only avoid repainting whole 
lines that have not changed, rather than checking every single character.  
Note - QRegion is not designed to handle a large number of very small regions.
