f50a3af1b7 Handle recursion from motion event handlers
If a motion event handler (or other handler running from the flush-events
phase of the frame clock) recursed the main loop then flushing wouldn't
complete until after the recursed main loop returned, and various aspects
of the state would get out of sync.

To fix this, change flushing of the event queue to simply mark events as
ready to flush, and let normal event delivery handle the rest.

b2113b7384 gdk: Add gdk_cursor_new_from_surface
We need this to be able to handle scaled cursor images.
We implement the new _from_pixbuf by converting to a surface and
assuming the scale was 1.

e4aa9f05ae GdkDisplay: handle multiple calls to _gdk_display_pause_events()
Since events can be paused independently for each window during processing,
make _gdk_display_pause_events() count how many times it is called
and only unpause when unpause_events() is called the same number of
times.

a69285da08 Compress motion synchronized with the paint cycle
When we have pending motion events, instead of delivering them
directly, request the new FLUSH_EVENTS phase of the frame clock.
This allows us to compress repeated motion events sent to the
same window.

In the FLUSH_EVENTS phase, which occur at priority GDK_PRIORITY_EVENTS + 1,
we deliver any pending motion events then turn off event delivery
until the end of the next frame. Turning off event delivery means
that we'll reliably paint the compressed motion events even if more
have arrived.

Add a motion-compression test case which demonstrates behavior when
an application takes too long handle motion events. It is unusable
without this patch but behaves fine with the patch.

b5cfdf2db4 gdk: Add internal API to deal with touch implicit grabs
The necessary information about a touch implicit grab is stored in
GdkTouchGrabInfo structs, these are meant to be transient to the
touch sequence.

8689921b90 gdk: Generate crossing events around touch devices' press/release
Anytime a touch device interacts, the crossing events generation
will change to a touch mode where only events with mode
GDK_CROSSING_TOUCH_BEGIN/END are handled, and those are sent
around touch begin/end. Those are virtual as the master
device may still stay on the window.

Whenever there is a switch of slave device (the user starts
using another non-touch device), a crossing event with mode
GDK_CROSSING_DEVICE_SWITCH may generated if needed, and the normal
crossing event handling is resumed.

5b014bfdfb gdk: Keep track of the last slave device used
This last slave device (stored per master) is used to fill
in the missing slave device in synthesized crossing events
that are not directly caused by a device event (ie due to
configure events or grabs).

44c02fcbb1 API: gdk: Change get_drag_window() API
The previous function gdk_drag_get_protocol_for_display() took native
window handles, so it had to be changed. Because it didn't do what it
was named to do (it didn't return a protocol even though it was named
get_protocol) and because it doesn't operate on the display anymore but
on the actual window, it's now called gdk_window_get_drag_protocol().

c332ac207a gdk: Remove GdkEventClient
... and all APIs making use of it.

That code like it hasn't been touched in years, Google codesearch
didn't find any users and most importantly it's a horrendous API, so
let's just make it die instead of having to port it over to
non-GdkNativeWindow usage, which would be required for multi-backend
GDK.

d72d19d247 API: gdk: Remove gdk_display_set_device_hooks()
There's no usecase for them, so remove them before we have to commit to
keeping an API.

Make the hooks private for now, actually removing them will come in
followup patches.

no point in having the standard GObject clas macros anymore either.

af7afbbe06 gdk: Allow display subclasses to override the type used for windows
We want to have different window types for different displays, so we can
write code like this:

  #if GDK_WINDOWING_X11
    if (GDK_IS_X11_WINDOW (window))
      {
        /* do x11 stuff */
      }
    else
  #endif
  #if GDK_WINDOWING_WAYLAND
    if (GDK_IS_WAYLAND_WINDOW (window))
      {
        /* do wayland stuff */
      }
    else
  #endif
      {
        /* do stuff for unsupported system */
    }

This requires different GdkWindow types and we currently don't have
that, as only the GdkWindowImpl differs. With this method, every backend
defines a custom type that's just a simple subclass of GdkWindow. This
way GdkWindow behaves like all the other types (visuals, screens,
displays) and we can write code like the above.

Move everything dealing with compound text to be X11 specific
Only gdk_text_property_to_utf8_list and gdk_utf8_to_string_target
are kept across backends, so add vfuncs for these.

Also, remove the non-multihead-safe variants of all these.
