SUMMARY
The scrollbar preview does not render with fixed char length, this breaks ascii art.

STEPS TO REPRODUCE
1. Open a ascii art document (scene release .nfo is a good one)
2. Use the scroll preview on the side to navigate
3. Notice the art looked broken since fixed spaces for white spaces is not respected.

OBSERVED RESULT
Bad ascii art image

EXPECTED RESULT
Nice ascii art image

Ok, I see, the pixel painted stuff in the scrollbar minimap are off.

KateScrollBar::updatePixmap() has issues with tabs. We not just ignore the configured tab width but the whole loop will not handle tabs well. We skip over chars and we don't align the tabstops.
