commit a9b0b4c75a6dc7282f7cfcaef71413d69f7f0731
Author: Egmont Koblinger <egmont gmail com>

widget: Implement smooth scrolling
Scroll the history (scrollback buffer) by pixels rather than rows.
This gives a better user experience especially with touchpads.
Also, use the extra area at the bottom (if the window is not
grid-aligned) to show some text when scrolling.
