I've made a change to the "switch" layer type that is very useful but also, unfortunately, backwards-incompatible (I've updated all of the instruments currently in the base package).
In its old version, the switch layer looked like this: <layer> <type>switch</type> <property>/foo/bar</property> <layer> ... </layer> <layer> ... </layer> </layer> If the /foo/bar property had a true boolean value, the first child layer would be used; otherwise, the second would be used. In the new version, the switch layer looks like this: <layer> <type>switch</type> <layer> <condition> ... </condition> ... </layer> <!-- repeat as many times as needed --> <layer> ... </layer> </layer> The first layer with a true condition gets used, no matter how many layers there are. This approach allows for simpler and more elegant tests in animating 2D instruments.
