Problem description: Tab-titles that are too long to fit into a tab get faded out.

                     On big endian this is broken and instead of fading out, the

                     tab gets white and the font transparent, leading to an unreadable

                     tab-title

Solution: This is not a real solution, but a hack. The real solution would have been

          to byte-swap the correct buffer, but I could not find it.

          So the next best thing is to deactivate the fading-effect. Now all tab-titles

          are readable, albeit not as pretty to look at as they could be.

Side-effects: I have not yet found an unwanted side-effect.
