[Feature] Include brush selection and changes to properties in .dprec #1489
Description
Being able to watch time lapses of whenever someone makes something is a very powerful way for me to learn how someone does something in Drawpile... But the experience is incomplete without showing which brushes are changed and what their properties become during the strokes.
This often leaves questions on what tools they could be using, or what if they adjusted a certain other property needed to achieve the effect properly. Maybe the artist is using a really specialized set of brushes that, while they don't seem like much at first glance, actually perform some very strong behaviors that can make a difference.
