Demo, blur, render, json

[OnePeople-source]

Hello. I really like your library. Thank you very much for such a great job. First, in your demo application, the scale animation button has an artifact (screenshot attached). Second, have you considered the blur function for the rectangle background taking into account the background? Third, I use your json parser, namely the MyJsonDoc.childnodes['contribs'].childnodes[i] structure, but if some element is missing, an exception pops up, is it possible to add a nil check there. Fourth, a modern request for enabling location detection needs to be added to geolocation. And one more thing, callback methods are used a lot in Android, they have to be delegated manually, maybe you know some automation tools for this process. Thank you again for such professional work.
