77b8495bc4 x11: Query pointer devices' scroll valuators on toplevel enter events
We used to "invalidate" scroll valuators, so the next scroll event could
be used as the base for the next scroll deltas. This has the inconvenience
that it invariably consumes the first event received after enter and,
due to interactions with WM overeager passive button grabs, there's a
possibility we don't scroll at all if we receive interleaved "smooth
scroll" XI_Motion events and XI_Enter events (Normally triggered by regular
scroll wheels in mice).

In order to fix this, and at the expense of some sync-call overhead on
XI_Enter events (one XIQueryDevice call per slave device), query the
current scroll valuator state for all the slaves of the entered pointer,
so we do know beforehand the right base values. If new devices are plugged
while the pointer is on top of the client, the initialized scroll values
will match the valuators'.

0f3995a446 x11: Avoid X error traps within server grabs
gdk_x11_device_xi2_window_at_position() may attempt to push/pop
a few error trap pairs while traversing the window tree. Move it
outside the server grab, and around the multiple XIQueryPointer
calls we may do here.

2feaf8f970 xi2: Don't set button mask 4 and 5
We interpret buttons 4-7 as old-school scroll events, so it does
not make sense to add these to the mask. Also fix an off-by-one
in the loop here, buttons_mask is 1-based.

4cae9bdd05 x11: Store last axes from device
And use these for the missing axes if the valuator mask is incomplete.
This used to work fine on tablets because the Wacom driver ensures all
valuators are sent, which is not true if using the evdev driver.

a53a931755 x11: Unset GdkX11DeviceXI2 scroll valuators on device change
Scroll valuators were being just appended again and again, leading
to 1) a growing memory issue anytime a device changed 2) the first
scroll valuators to stay permanent on the application lifetime, as
the first stored valuators would always match.

e8b38fedbd gdk: Convert mouse position to doubles, add new getters
We've long had double precision mouse coordinates on wayland (e.g.
when rotating a window) but with the new scaling we even have it on
X (and, its also in Xinput2), so convert all the internal mouse/device
position getters to use doubles and add new accessors for the
public APIs that take doubles instead of ints.

525e5cff04 x11: Initial cut at supporting window scaling for X11
If you set GDK_SCALE=2 in the environment then all windows will be
scaled by 2. Its not an ideal solution as it doesn't handle
multi-monitors at different scales, and only affects gtk apps.
But it is a good starting points and will help a lot on HiDPI
laptops.

ea6ac66392 x11: make _gdk_device_query_state report the master's device state
Calling XIQueryPointer() on a slave device is going to trigger a
BadDevice X error. So in case we query a slave device state, ask the
master device instead.

3dd5e88c07 xi2: Normalize scroll deltas
XI2 provides us with an increment for each scroll valuator,
and by dividing the delta by the increment, we obtain normalized
values in some abstract 'scroll unit'.

For mouse wheels, the evdev driver reports an increment of -1,
so doing this division fixes the inverted scrolling with wheels
that we've seen recently.

147cdd8465 devicemanager,xi2: Implement smooth scrolling
XInput >= 2.1 allows for implementing smooth scrolling,
reporting the different scrolling axes as valuators.
Any change in those will be reported as GdkEventScroll
events with delta_x/y information.

the older kind of scroll events is still handled, and
emulated in devices able to provide smooth scrolling,
setting _gdk_event_set_pointer_emulated() in that case.

de9a082ddb x11: Make headers identical no matter if we run with or without XI2
Previously we weren't installing the device headers when compiling
without XINPUT support. But we would include them from gdkx.h, so
essentially the build was broken.

With this patch the types will exist but not do anything.
