Subject: [PATCH 1/3] desktopManager: Handle TOUCH_UPDATE/END events explicitly
for rubberband
These events need specific handling for Wayland, as we do not get emulated
pointer events in that platform. Handle these for rubberband selection.

Subject: [PATCH 2/3] desktopGrid: Handle TOUCH_BEGIN events explicitly
We do not get pointer emulated events on Wayland, so touch events should

Wayland does not get pointer emulated events, so we must handle TOUCH_BEGIN/
