string.isEmpty() implies string.isNull(), so you don't need string.isNull().

Done.

Shouldn't this be a FIXME?

FIXME: Distance calculation is not possible for SVGPoint right now. We need the
distance for every single value.

[kouhei (in TOK), 2014/01/20 01:10:26]

This shouldn't be a FIXME. SVGPoint is never animated by itself (only its list
is animated), so calculateDistance is not needed. This is used for paced
animation.
