the mirrored content of the source window. See the next steps
for 

misc:
* added debug+desktop only shortcut 
* rotating square display now update the root window. 

Next steps:
* Mirror cursor
* Modify OutputConfigurator to fallback to software mirror mode.
* Scale the root window size for mirror window so that 
it has the same size as the source root window. 
* Copy texture from soruce window to dest window. 
* Handle device scale factor/cursor scaling.
