Fix transform for ordinal→quantitative scales.

Previously, invalid transform attributes were being set for an
ordinal→quantitative scale transition, because entering ticks were
undefined in the old (ordinal) scale, and exiting ticks were undefined
in the new (quantitative) scale.

Fixes #1620.
Simpler update between ordinal & quantitative scales.
Avoid flipping longitude near ±π.

When computing the midpoint between two points both at longitude -π, there was a
chance that atan2 would return +π rather than -π. Now, we check whether the
points to interpolate lie (approximately) on a meridian; if they do, we can
approximate by using linear interpolation of longitude rather than atan2. This
fixes #1635 which was caused by new trig implementations in Chrome Canary.
