Otherwise, it can be one of many supported easing functions. See easing.h for available functions. The fifth argument is another Lua script that will be executed when the interpolation provided in parameter 3 finishes. The URI is interpreted using a wildcard in which ‘’ is expanded to ‘(.)’ and bracketed components ‘{ }’ are interpreted as group tag names. Then, the passed value will be set on all properties that fit the regex + group name combination.
