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.

The warnings are only silenced in code that is conditionally used on
older platforms. When the newer (non-deprecated) API is available, it
will be used.
