Introduce separate mouse release and mouse drag (move while pressed)
events: MouseLeftRelease, MouseLeftDrag, MouseRightRelease etc,
to allow binding them to actions independently from mouse press events
(MouseLeft, MouseRight etc).
This change:
- Makes it possible to handle mouse release and drag for arbitrary mouse
events and actions (including Lua actions), not just for MouseLeft as
in the current code.
- Fixes issue #2599 with PastePrimary and MouseMultiCursor actions:
selection is pasted not only when pressing MouseMiddle but also when
moving mouse with MouseMiddle pressed; similarly, a new multicursor is
added not only when pressing Ctrl-MouseLeft but also when moving mouse
with Ctrl-MouseLeft pressed.
My initial approach was not to introduce new events for mouse release
and mouse drag but to pass "mouse released" info to action functions
in addition to *tcell.EventMouse to let the action functions do the
necessary checks (similarly to what MousePress is already doing). But
then I realized it was a bad idea, since we still want to be able also
to bind mouse events to regular key actions (such as PastePrimary)
which don't care about mouse event info.
