Button hold event does not get transmitted or generated #328

issue description

I have a trackball and the gsetting for scroll wheel emulation only works if the input-remapper is not forwarding the device.

Expected behaviour on pressing and holding the button: moving the physical ball scrolls instead of moving the cursor

Observed behaviour: moving the ball moves the cursor

I initially thought that this is related to #185, which is why I included all this info. But a deeper dig revealed that this is related to the transmission of the hold value. Which, according to the comments in the code is not being forwarded. But the event is not being generated on its own, so I think a transmission is necessary.

Quoting https://github.com/sezanzeb/input-remapper/issues/49#issuecomment-831622386:

X/Wayland do their own key repeat, the kernel key repeats are filtered in libinput and would only affect a VT

I really wish there was someone who really knows GNOME internals who contributes to this project. There are so many problems with environments that I just don't understand at all.
