Inject finger input whenever possible

Even if the pointer is a mouse, inject it as a finger unless it is
required to be a mouse, that is:
 - when it is a HOVER_MOUSE event, or
 - when a secondary button is pressed.

Some apps/games only accept events from a finger/touchscreen, so using a
mouse by default does not work for them.

For simplicity, make this change on the server side just before
event injection (so that the client does not need to know about this
hacky behavior).
