Partial Buffer Demo v1.0.2

Hi all,

We updated the Partial Buffer Demo at Github, this demo shows how to fully use a display with low memory resources by not having a full back buffer.

This version mainly fixes some UI flush issues.

If you want to learn more about the partial buffer concepts visit the documentation below.

Happy Coding!
