The default focus interface uses the button count to determine
whether we should update the pointer focused surface. When releasing
an implicit grab, we need to send the button release events to the
implicitly grabbed surface, so we can't reset the focus surface too
soon. We already explicitly set the focus at the end of implicit
grabs, so counting the buttons after is perfectly fine.
If we send out a configure notify for a window and then have some
other kind of state change, we need to make sure that we continue
to send out that new size, rather than the last size the client
sent us a buffer for.
In particular, a client might give us a 250x250 buffer and then
immediately request fullscreen. We send out a configure for the
monitor size and a state that tells it it's full-screen, but then
it takes focus, and since the client hasn't sent us a buffer for
the new size, we tell it it's fullscreen at 250x250.
Fix this.
If we attach to a MetaWindow that disappears before the idle fires,
we'll notice that we can't associate the window properly again and
try to access data on the MetaWindow struct, which might crash.
Install a weak ref that ties the lifetime of the idle to the lifetime
of the MetaWindow.
It seems every GTK+ app does this for some reason at startup. This
is really unfortunate, since we'll have to create and destroy a new
MetaWindow really quickly.
Scale surfaces based on output scale and the buffer scale set by them.
We pick the scale factor of the monitor there are mostly on.
We only handle native i.e non xwayland / legacy clients yet.

Advertise the scale factor on the output and transform pointer and damage
events as well as input and opaque regions for clients
that scale up by themselves i.e use set_buffer_scale.
We do not scale any 'legacy' apps yet.

Ugh. So in the fullscreen case, we need to make sure to specify that
it's a MOVE_ACTION so that we move to the saved position, but we
can't do that in the resizing case since we need to use the resized
rectangle.
The flags are really hurting us here. Perhaps we should make it the
client's responsibility to specify a complete rectangle which we
could resize to; then the weird-o logic would be self-contained in
each front-end.
I'm not convinced this covers all cases, especially when we could have
a dangling weird state pointer, but it fixes our existing two testcases.
Restoring the position in our move_resize_internal implementation
is too late. We need to do it at ack-time, before we hand off the
new position to the constraints code.
For the server-initiated resize case, like unmaximize or some forms
of tiling, we dropped the x/y of the server-assigned rectangle on the
floor, which meant the surface didn't move to where it needed to be in
that case. Now, save it internally, and combine it with the dx/dy passed
in during attaches to figure out where we actually need to be.
Make sure to only use it for when we send out a configure notify. We
should use the passed in rectangle for other scenarios, like a
client-initiated resize.
This fixes incorrect surface placement after unmaximization.
