This will be used to replace some of the hooks that are used to call
into window.c, so that the workspace index property is properly kept up
to date.
We can't name the property "index" since it causes conflicts with the
meta_workspace_index method. This should really be called
meta_workspace_get_index, but oh well.
I accidentally broke this in commit a119ea9. The code was considerably
more complicated than it needs to be, so let's replace it with a
g_list_find and nothing more.
Scanning over the hash table of XIDs is a terrible idea. Not only were
we excluding Wayland windows, but we were also looking at alarms and
barriers, too. We were lucky that that only contained GObjects where
our checks would work.
MetaGrabOp is painful and tedious to work with, because it's a
sequential series of values, meaning we have to use a giant unreadable
switch statement to figure out some basic things about the value.
To solve this, modify the encoding for MetaGrabOp and for the specific
window grab operations so that they're a set of bitflags that we can
easily check.
We've long used a switch statement on the grab operation to determine
where events should go. The issue with MetaGrabOp is that it's a mixture
of a few different things, including event routing, state management,
and the behavior to choose during operations.
This leads to poorly defined event routing and hard-to-follow logic,
since it's sometimes unclear what should point where, and our utility
methods for determining grab operations apart can be poorly named.
To fix this, establish the concept of a "event route", which describes
where events should be routed to.
It turns out that Clutter doesn't actually filter NumLock / ScrollLock /
CapsLock from button events due to its terrible event translation code.
Check only the grab mods to check if it's unmodified.
Popups could not set the cursor image, because the cursor tracker would
ignore window cursors if we had a popup active. The correct condition to
check for is already in should_block_wayland. Rename this to the more
sensible name windows_are_interactable, and use it in the cursor tracker.
Since commit 467465c99c we use meta_stage even on x11 which sets
clutter_stage_set_user_resizable to FALSE.
This messes things up because we ought to ignore the properties on the window
but we apperently didn't.
There is no reason why we'd want to manage the stage window.

Instead of returning a value based on whether or not we handled it, we
have this logic: either we have taken a grab on the window, in which
case we have a grab op and have handled it ourselves, or we did not take
a grab and *need* to replay the event to the window.
Handle this in events.c by checking the grab operation in the same way
that we check the other grab ops.
This is an accidental regression from 7a109a1. If we mark the event as
handled, then we *need* to set grab_op, or do some other sort of
behavior, since we have a grab.
meta_backend_get_keymap is supposed to return a static keymap, not a new
one every time. Cache it internally. We don't update it when the keymap
changes on the server, but we'll do this soon.
