Without this event Components such as Button would remain in a hover
state indefinitely after being clicked on a touch screen. The simulated
event matches the behaviour of the other platforms.

Without this MouseInputSource::getComponentUnderMouse() will report a
stale value after moving the cursor within a single peer using
MouseInputSource::setRawMousePosition().

This fixes an issue where e.g. pressing 'return' to select an item from
an IME list would directly insert a newline character, rather than
selecting the entry.

This is a breaking change - see BREAKING-CHANGES.txt

When using RDP to access a Fedora machine running Gnome, the only
available colourmap is 32-bit. The old implementation caused GUI apps to
crash when they attempted to use a null colourmap pointer.

When using Universal Control, the system seems to translate mouse scroll
events into swipe gestures, meaning that the gesture position is not
constant during the gesture.
