gamescope's EIS ("Gamescope Virtual Input") advertises pointer/
pointer_abs/button but never a touchscreen — so in Game Mode every
remote TouchDown/Move/Up was dropped on the floor (Desktop Mode works
via KwinFakeInput, which does touch). Headless KWin's libei has the
same gap. Instead of dropping: degrade to a single-finger absolute
pointer — down = abs-move + left press, move = abs-move, up = release —
synthesized through the normal Mouse* inject paths so region mapping,
held-state tracking, and release_all apply. First finger drives the
pointer; later fingers are ignored (a pinch degrades to a drag). A
touchscreen device appearing later takes over on the next touch —
checked per event, never latched.
