Hutterer: GNOME tablet support papercut fixes

Peter Hutterer has writtena summary of "papercut fixes" for GNOME tablet support that areplanned to ship with GNOME 47.

If you're an avid tablet user, you may have multiple stylus tools -but it's also likely that you have multiple tools of the same typewhich makes differentiating them in the GUI hard. Which is why they'rehighlighted now - if you bring the tool into proximity, the matchingimage is highlighted to make it easier to know which stylus you'reabout to configure. Oh, and in the process we added a new SVG for AESstyli too to make the picture look more like the actual physicaltool. The <blink> tag may no longer be cool but at least we can discoour way through the stylus configuration now.
