F-Curve Drawing - Smoother curves

Bezier curves are now drawn smoother (i.e. less segmented), especially
for curve segments where there is a very large vertical displacement
over a short period of time (i.e. 120 degrees rotation over 1 frame)
and/or often when zoomed in a bit too.

- Made the resolution calculation take the vertical distance into
account too, instead of just the horizontal distance.
- Segment multiplier changed from 3 to 5, as this seems to give better
zoomed-in performance.
