v9.8.1

Rotating to 270° now shows your content the right way up.

On rotating panels, setting the display to 270° used to look identical to 90° — the background, mask, and metrics were all a half-turn off. Now the whole composite flips to follow the physical rotation, so 90° and 270° are proper opposites the way they should be.

This covers the smaller rotating panels (320×240 / 640×480); the widescreen panels handle rotation on a separate path that's still being worked on, so they're unchanged in this release.

Maintainers: a diagnostic replay tool now boots and replays a user's trcc report with no hardware (dev/mock_gui.py --issue N --replay --check), making device-specific bug reports much faster to reproduce.
