Rendering Problem with Android Studio

[lpellegr]

Thank you for your great library! Although it works pretty well with deployed apps, when I use it on Android Studio, the Preview Windows indicates some rendering errors. It would be great if your library could be used with the preview mode of Android Studio. Below is the stacktrace:

I found the root of the problem (ScaleSpan with multiplier value at 0f) and fixed it. The update has been pushed to maven central and should be synced soon. New version with the fix on maven is 1.3.
