Rather than add but-yet-another bool, I think we should probably follow the
pattern already established by PlatformMouseEvent which has a
'SyntheticEventType' member which can be 'FromTouch'.  Most often that should
just be propagated down from the PlatformMouseEvent to the MouseEvent - not
specified explicitly.
