4 # animated attributes can be defined as key(time) = value.

5 # time defaults to 0 if missing. time values can have an optional s suffix,

6 # signifying seconds, otherwise they are assumed to be in milliseconds.

10 # randomized values have a pair of values/vectors separated by a tilde:

11 # center ~ range. If the range is missing, it's assumed to be 0.
