Configuring Booleans in window rules

Hi,

In the window rule properties dialog non-Boolean settings have a check 
box before the value widget (text field, slider or whatever is 
appropriate for the type).  The check box indicates whether the setting 
is active, i.e., the rule should apply it for matched windows.  This is 
not explained in the dialog, but the value widget is only enabled when 
the check box is set, making the semantics somewhat discoverable or at 
least guessable.

However, Boolean settings only have a single check box, which is 
apparently supposed to be tristate: a minus sign indicates that the rule 
should not change the setting.  So how do I set the check box to this 
state?  Clicking only toggles between checked and blank.

I don't much like the tristate check box because it is inconsistent with 
the way other types are handled.  Having two check boxes next to each 
other would also be confusing, perhaps more so.  Maybe we should use 
something else as the Boolean value widget to distinguish it from the 
activation check box.  The switch of GTK 3 would be just the thing, but 
with GTK 2 it would probably have to be a toggle button.  Or we could 
use something other than a check box for indicating if a setting is active.
