Some platforms should not allow quitting ScummVM. For example the Apple's
HUG for iOS state that we should "Never quit an iOS applications
programmatically". Adding the kFeatureNoQuit allows those backend
that need it to remove the possibility to quit the application.
The keyboard repeat event generator is used when building against SDL1.
Previously the repeat events would generate based on the event stream
produced by the keymapper which is not guaranteed to have matching up
and down events in the case the keymaps are changed while a key is
pressed.
Fixes#11417.
Game controller input is now enabled whenever a compatible device is
connected. The keymapper's keymaps are refreshed when a joystick is added
or removed.
Fixes#10366.
The Virtual Mouse is meant to provide a way to control the mouse cursor
on system without a physical mouse. It provides keymapper actions that
are expected to be bound to game controller axes or buttons.
Backends can still (and do) generate such events. This works around an
issue with the keymapper where the "DOWN" event would be mapped to a
key, but the corresponding "UP" event would be mapped to another one due
to a keymap change. The keyboard repeat generation system would believe
the key to be still pressed and send a continuous stream of repeat
events.
Ideally the keymapper should be fixed to always generate matching event
pairs. However this source of an infinite stream of events still looks
like trouble waiting to happen to me. Hence disabling it by default.
Normally with SDL, a mouse motion event will be sent after the
system mouse cursor has been moved by a call to
SDL_WarpMouseInWindow, but if the system cursor cannot be moved
(e.g. because the window does not have mouse focus), games still
need to receive these mouse events so they can successfully update
the mouse position internally. Otherwise, games continue to think
the mouse is still in the original position and will continue to
try to perform whatever action is associated with that mouse
position.
