Changing the AnimationState state from an "end" listener is problematic even when the entry is cleared before the listener, so better to make the track that is ending available to the listener.
Version 1 of the license didn't make sense: it required a Spine license to use the Spine Runtimes at all. This means if you used the Spine Runtimes in your application, anyone who purchased a copy of your application also needed a Spine license to use the runtimes. This was not the intent!
Version 2 of the license fixes this by allowing anyone to use the Spine Runtimes but only for internal use. When you purchase Spine, the Spine license (http://esotericsoftware.com/spine/files/license.txt) grants you the right to make and distribute derivative works of the Spine Runtimes. Now it makes sense: making and distributing applications with the Spine Runtimes requires a Spine license, but anyone can run that software without needing a Spine license.
With this fixed, I hope we never need to change the license again!
Changed from New BSD to a custom license. The new license requires a Spine license to use the code. If you have a valid Spine license, you can do whatever you like with the code. This should not be a problem for anyone using the runtimes with Spine, nothing changes. If using the runtimes without a Spine license, you now need a Spine license. This is because the runtimes were created explicitly to be used with Spine.
Missing semicolons can cause trouble when minifying
or concatenating Javascript sources. The last one
actually did cause trouble when being followed by
an IIFE after concatenation.
Tested the 'toColor' function with 'ffffff00'.
The returned result (in r,g,b,a) was 1,NaN,1,257.
The correct result should obviously be 1,1,1,0.
The hex substring was being done incorrectly.
