+Subject: [PATCH 1/2] backends/native: Swap BTN_STYLUS and BTN_STYLUS2
+
+BTN_STYLUS is the lower one and traditionally (read: in X) maps to
+middle button (2), BTN_STYLUS2 is the upper one and traditionally maps
+to right button (3).
+
+This is also what GTK does and our desktop actions too map MIDDLE to
+BTN_STYLUS and RIGHT to BTN_STYLUS2.
+
+See also gtk!6168

+Subject: [PATCH 2/2] backends/native: Fix clutter button number assignment to

+
+Commit 947c636275 meant to swap BTN_STYLUS* buttons, not BTN_MIDDLE/RIGHT
+as used by pointing devices. This was also missed during review.
