Is this preference really necessary? It just compounds the confusion. 
CTRL (keyboard device) and ALT (application modifier) operate at 
different levels of abstraction.

It is about time we contained traditional modifiers like CAPSLOCK/SHIFT 
and CTRL within input plugins. Let plugins use these modifiers to map 
key code 16r40..5f<->16r60..7f and 16r40..16r5f->16r00..16r2f.

Only ALT (CMD on Mac) modifier needs to be passed to the image and 
handled its input handlers. Mouse buttons should be checked only with 
ALT/CMD and not low level modifiers.

This separation of modifiers should simplify both the VM and the Image 
code and be consistent with their intended meaning.

All we need is a new preference that states that VM will handle 
machine-specific modifiers ;-).
