The toolbar and the slider (itself) look good now on the Carbon port
(thanks, Yamamoto-san!) , but the position of the whole scrollbar
isn't quite right depending on the font chosen. Even if the window
size has to be a multiple of some nominal character width, I still
think the scrollbar should be positioned on the right edge of the
frame (or the window, if horizontally split). In the attached
screenshot you can see that the right edge of the scrollbar is barely
visible, which was certainly not intended by the designers. The
resizing-corner looks ugly as well because of the scrollbar shadow
that is drawn there. Standard windows (i.e. using the OS toolkit)
look like shown on the third screenshot attached.
