cf1fbdf8b5 gdk: Add gdk_event_get_seat()
It currently fetches the seat from the event device, will be changed
in future commits.

1c856a208f Rename master and slave device
We already use the "logical/virtual" and "physical" names in the
documentation, there's no reason to use loaded terms just because X11
uses them.

4317c008f0 Address review comments
We were casting scroll events to motion events
rather carelessly. Don't do that.

c9fad25131 gdk: Rename gdk_motion_event_get_history
Scroll events can have history too, so make a
getter that works for both. This drops the
gdk_scroll_event_get_history getter that was
added a few commits earlier, since we now
store scroll history in the same way as
motion history.

Update the docs, and all callers.

b9cde6f8ea Keep scroll history
Similar to how we keep motion history for compressed
events, keep scroll history for compressed scroll
events.

86eece78b1 gdk: Compress scroll events
Only return one accumulated scroll event per frame.
Compress them by adding up the deltas.

Still missing: a way to capture history, like
we do for motion events.

79105962a7 Remove position from GdkScrollEvent
Scroll events do not have a position, so they shouldn't implement the
GdkEventClass.get_position() virtual function; nor they should have an x
and y fields that never get updated.

ddd113ac98 Annotate gdk_motion_event_get_history() correctly
We moved from returning a list to returning a C array, and this requires
a change in the annotations.

99c3928cec keymap: Cache key info
We currently calling gdk_display_map_keyval up to
once per key event per shortcut trigger, and that function
does an expensive loop over the entire keymap and
allocates an array. Avoid this by caching the entries
in a single array, and have a lookup table for finding
the entries for a keyval.

To do this, change the GdkKeymap.get_entries_for_keyval
signature, and change the ::keys-changed signal to be
RUN_FIRST, since we want to clear the cache in the class
handler before running signal handlers. These changes are
possible now, since keymaps are no longer public API.

f28aa1ba02 Restructure the GdkEvent type hierarchy
GdkEvent has been a "I-can't-believe-this-is-not-OOP" type for ages,
using a union of sub-types. This has always been problematic when it
comes to implementing accessor functions: either you get generic API
that takes a GdkEvent and uses a massive switch() to determine which
event types have the data you're looking for; or you create namespaced
accessors, but break language bindings horribly, as boxed types cannot
have derived types.

The recent conversion of GskRenderNode (which had similar issues) to
GTypeInstance, and the fact that GdkEvent is now a completely opaque
type, provide us with the chance of moving GdkEvent to GTypeInstance,
and have sub-types for GdkEvent.

The change from boxed type to GTypeInstance is pretty small, all things
considered, but ends up cascading to a larger commit, as we still have
backends and code in GTK trying to access GdkEvent structures directly.
Additionally, the naming of the public getter functions requires
renaming all the data structures to conform to the namespace/type-name
pattern.

14be8f6b73 Remove uses of modifier intents in gdkevents.c
This removes the use of the context menu and shift group
intents in gdkevents.c. If it turns out to be important,
we need to introduce vfuncs for gdk_event_triggers_context_menu
and gdk_event_matches.

0a96a483c6 gdk: Redo key events
Add all of the keyboard translation results in the key event,
so we can translate the keyboard state at the time the event
is created, and avoid doing state translation at match time.

We actually need to carry two sets of translation results,
since we ignore CapsLock when matching accelerators, in
gdk_event_matches().

At the same time, drop the scancode field - it is only ever
set on win32, and is basically unused in GTK.

Update all callers.

e8330c5eec Add gdk_event_matches

GtkShortcutTrigger to GdkEvent, which greatly reduces
the amount of keymap api use outside of GDK.

be4b34aa8f events: Use GdkDrop as event sequence
This allows treating drop events like touch events, which GTK groups by
event sequence.

It's a bit ugly that we just case the GdkDrop pointer, but event
sequences are only meant to be unique pointer ids, so it's fine.

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.

b1eaa502df events: reorganize getters

event struct access with getters.
