In controversy to that, I remember KMail having had a hardcoded frame size of 
1 pixel at the time around the import of Plastik into CVS. This was meant to 
make KMail "look better" with Keramik (the default style at that time) by 
removing the visible "3 pixel line" (splitter aligned to 2 px frame).

But the problem was that this didn't work with the kind of frames used in e.g. 
Plastik (By the time I have changed KMail to use the style's frame width for 
all styles != Keramik).

This is also why I'm generally not in favor of hardcoding something 
gui/style-related into applications: It won't be possible anymore to change 
it centrally (e.g. in a QStyle), so it means additional work for someone who 
might decide to change this behavior in the future (for whatever reason).

One possible solution for instantly providing "Fitt's law" in a wide range of 
applications at once: Position scroll bars on top of the outer frame (e.g. 
when there is a horizontal scroll bar there would be only three frame borders 
The trolls promised me to add such a QStyle switch for 
QAbstractScrollArea-based widgets in a future release of Qt.

In a clearly defined manner like this and if feasible (e.g. it's probably a 
bad idea to remove the frame of tab widgets), this sounds good to me.
