Add mobile gestures for Transformer package

[jdnichollsc]

Hey mate, congrats for building this amazing PixiJS package!

I was wondering if you're planning to support mobile Gestures like TikTok or Instagram while adding stickers? I mean, using 2 touch pointers for rotating and scaling the container?

Any comments is really appreciated, thanks for your help!

Hi Nicholls, I currently don’t have the bandwidth to implement new features in this library. I’m happy to review pull requests and publish a new version of the package, however. Regards, Shukant Pal
