These devices set the LIBINPUT_DEVICE_CAP_TABLET flag, and emit a lot more axis
information then mice and touchpads. As such, tablet events are in a whole new
group of events that is separate from everything else.
In this commit, only X and Y axes are reported in libinput.
Based off the patch originally written by Carlos Garnacho

Fixed point numbers can easily overflow, and double to fixed point
conversion is lossy. Use floating point (double) where fixed point
numbers where previously used and remove the li_fixed_t type.

Remove compiler warning about signed/unsigned comparison. And while we're at
it, rename i to _i in the macro to avoid name clashes.

Instead of having the user manage added and removed fd's as well as the
fd used for creating evdev devices, introduce a libinput object that
itself has an epoll fd.
The user no longer manages multiple fd's per libinput instance, but
instead handles one fd, dispatches libinput when data is available, then
reading events using libinput_get_event().
libinput_event's are now per libinstance, but divided into categories.
So far the only category is device events. Device events are categorized
by the presence of a non-NULL device pointer in the event.
The current API usage should look like:
struct libinput libinput = ...;
struct libinput_event *event;
if (libinput_dispatch(libinput) != 0)
return -1;
while ((event = libinput_get_event(libinput))) {
if (event->device)
process_device_event(event);
free(event);
}
