React Native pinch to zoom advanced
/**
* After some thoughts on this topic, I've decided to turn this gist along with other features into a library so you can zoom
* whatever you want, library you can find here https://github.com/Glazzes/react-native-zoom-toolkit.
*
* @author Santiago Zapata, Glazzes at Github <3
* @description This gist makes part of an article I'm writing about this topic (in spanish). This solution takes into account
* the linear algebra concepts and geometrical interpretation of the transform-origin property specification, this solution
* takes heavy inspiration from William's Candillon +3 year old video in this topic, however this solution brings it to the
* modern day along with a huge fix that prevents the origin from being displaced by an incorrect offset calculation after
* the first zoom interaction.
