I will say that light source rotation will add to the confusion. The
light source come from the top left of the screen (and the brain know
that!). I do not think that the light source should be rotated it is a
property of the all screen (example: with a 180 rotation raised will
become sunk!! with a 90 rotation you have a raised-sunk relief). Note
that for title the relief is not rotated (if you rotate you get
various catastrophic result).

Really I do not understand. How it is possible to say that a rotated
real button (a fg button) will be easily recognized than its normal
version. What I can understand is that some current config will
_globally_ look better with buttons rotation. If we add a new style
for that what will happen is that some config will not be fixed.
Then, as I think that buttons rotation is erroneous from the usability
point of view I do not think that I will have the time to implement
any buttons rotation.
