UI fixes:

- on setting lower DPI, the regions that were scrolled down would start moving down
  1 pixel on every draw. Caused by rounding error. (int + 0.1 vs int -0.1)
  (Ancient bug)

- circles used in outliner - to denote selection/active - now draw bigger, and better
  centered. (2.66 fix only)
