Bilal Elmoussaoui af8d90d1b5 display: Expose a helper for retriving guest position
When running an Android VM with GL support, Android somehow enforces
support for only touch events making it difficult to work with QEMU +
Android for devolpement / demo purposes without a touch screen.

This helper is useful for being able to emulate motion / click
events as touch ones
