41ef6e9fa5 transform: Add optimization for common case 
Transforming identity by an other transform does not mean we need to
painstakingly apply the individual steps of other to construct a new
transform, it means we can just return other.

Or in math terms:
  I * B = B
so just return B.

d7d7957b04 profiling: Avoid one extra printf 
We already format the message, no need to use
printf again to combine that with the kind string.

376f5eacbd profiling: Avoid criticals 
With events no longer GObjects, the type class is
longer around for peeking.

5ebe5be225 Stop exporting gtk_get_event_widget 
This is non-essential convenience API, and we
don't really expose events to applications anymore.

8823882f97 gtk: Stop using GdkEventKey 
We should just use GdkEvent, instead of taking
a GdkEventKey, and then cast it everywhere.

e062137b2c motion controller: Match focus event propagation 
Make the crossing event generation for pointer events
match what we do for focus now.

77aed615e8 Keep more event controller api private 
We don't want to expose the GtkCrossingData struct, and manually
feeding events to event controllers is not something we want to
encourage, going forward.

0c96b2d8f7 Bring back im context focus-in/out 
The key controller still needs to track focus,
in order to emit these signals when required.

cadeca74e2 Go back to ::enter/::leave for pointer changes 
These signals are behaving a little differently from
what ::focus-in/::focus-out used to do.

5a2f829a40 Split off GtkEventControllerFocus 
Split the focus tracking into a separate
GtkEventControllerFocus, and change the API one more time.
We are back to having ::focus-in and ::focus-out signals.

Update all users.

89c3a7ab24 wip: Add more information to crossing events 
Add fields for direct descendents to GtkCrossingData,
and populate them when emitting focus change events.

Also add accessors for these fields to GtkEventControllerKey,
and verify that they are set properly in the focus test.

Not done yet: Do the same for pointer crossing events.

6fd913b361 Some event struct packing improvements 
Rearrange a few things, and move some booleans
into the Any struct, by using a bitfield there.

Some more cleanup could be done - the flags field
with its PENDING and FLUSHED members appears
entirely unused. Nobody is setting those flags.

0fc2505ed6 Drop gtk_widget_event from API 
We don't want events to be injected randomly from
the outside. Plus, there's no way to create such
events from the outside now.

b1eaa502df events: reorganize getters 
Restructure the getters for event fields to
be more targeted at particular event types.

Update all callers, and replace all direct
event struct access with getters.

As a side-effect, this drops some unused getters.

31bf9da63a Strip const from GdkEvent

place.

23c67f8c67 New focus change handling 
Instead of relying on gdk's antiquated crossing events,
create a new GtkCrossingData struct that contains the
actual widgets, and a new event controller vfunc that
expects this struct. This also saves us from making sense
of X's crossing modes and details, and makes for a
generally simpler api.

The ::focus-in and ::focus-out signals of GtkEventControllerKey
have been replaced by a single ::focus-change signal that
takes GtkCrossingData as an argument. All callers have
been updated.

dd251d85c4 Pass translated coordinates outside the event

coordinates separately, when propagating events.
